Quantum's JVM external issues page for CROME


Installation of the JVM Appears to Fail

Note, during the installation of the JRE you should get a full screen installation wizard (this is typically blue or green and has a licencing set and an installation directory step). If only get one single small dialog popup, and a full screen installation program fails to appear your JRE will have not been completely installed and CROME will not be able to run.

The above issue might stem from a virus checking programs or other executable on Win95/98/NT/ME/2000/XP. If you do not seem to get a full JVM install you should try to

Since QuantumSI does not produce the JRE installer (i.e. they are created by Sun or IBM) we can not correct the occasional problems with various revisions and patches to the Win95/98/NT/ME/2000/XP operating systems.

A normal 1.3.1 (or 1.1.8) JVM install should have a licensing step like

In the event that the JVM does not install correctly and you later attempt to install the CROME client software, you will get an error message window as follows:

Such a message indicates that the needed Java base software (or an approved JVM version) was not found on your Win95/98/NT/ME/2000/XP computer. In this case CROME will not run.


Specific JVM releases

Known issues with various revisions of the Java Virtual Machine that impact CROME and have not yet been explicitly coded around. Note, there are many inconsitancies (several hundred) that have been conditionally fixed in CROME source for all major JVMs and this list. We only list those items below that have a major impact a customer or a potential customer using CROME.

Currently Quantum highly recommends the following JVM's for CROME. Note, the Java 2, release 1.4.2 is the fastest JVM on Win95/98/NT/ME/2000/XP and UNIX/LINUX platforms.

Win95/98/NT/ME/2000/XP
Java-2, J2SE release 1.4.2 Vendor: SUN j2re-1_4_2_12-windows-i586-p.exe

To fetch SIMPLY CLICK, if you don't get an autoexecute option try SHIFT CLICK WHEN FETCHING and save to your disk and execute outside of your browser from the approved list above.

If you are running a different version of the JVM you may simply install one of the JVMs from the list above and then re-install CROME (note this will not overwrite any of your reports, formulas or settings in your CROME application).

We appreciate feedback from both customers and non customers on other issues, please send them to the E-Mail address at the bottom of this page with a subject "CROME FEEDBACK".


Java 1, SUN JRE/JDK 1.1.5 - approved, no longer recommended (*1)

(CRITICALITY: LOW) Timezone support world wide is poor for example the two time zones CST and IST (China standard and Israel standard time under Solaris ) are (US) central standard time and India standard time in java. Thus international deployments need to be pretested and check for timezone inconsistancies.

(*1) Other JVMs are much faster i.e. Sun's Java 1 - 1.1.8 and Java2 - 1.3.1 and IBM's Java 1 - 1.1.7/1.1.8.

(FUNCTIONALITY: LIMITED) Very old (Java-1) JRE versions such as the 1.1.8 JRE will still work however CROME will automatically disable some of CROME's more recent advanced features. In additon Java-1 releases will typically run up to 40% slower than Java-2 releases.

(EOL: INFORMATION) Sun Microsystems has End-of-Lifed this release of Java (e.g. Java-1) if you must run a Java-1 varient please use JRE/JDK 1.1.8.


Java 1, SUN JRE/JDK 1.1.6

(CRITICALITY: HIGH) Problems too numerous to list, it was a short lived release.

(FUNCTIONALITY: LIMITED) Very old (Java-1) JRE versions such as the 1.1.8 JRE will still work however CROME will automatically disable some of CROME's more recent advanced features. In additon Java-1 releases will typically run up to 40% slower than Java-2 releases.

(EOL: INFORMATION) Sun Microsystems has End-of-Lifed this release of Java (e.g. Java-1) if you must run a Java-1 varient please use JRE/JDK 1.1.8.


Java 1, SUN JRE/JDK 1.1.7 and 1.1.7A

(CRITICALITY: HIGH) Bad JRE installer

(FUNCTIONALITY: LIMITED) Very old (Java-1) JRE versions such as the 1.1.8 JRE will still work however CROME will automatically disable some of CROME's more recent advanced features. In additon Java-1 releases will typically run up to 40% slower than Java-2 releases.

(EOL: INFORMATION) Sun Microsystems has End-of-Lifed this release of Java (e.g. Java-1) if you must run a Java-1 varient please use JRE/JDK 1.1.8.


Java 1, SUN JRE/JDK 1.1.7B - approved, no longer reccomended

(CRITICALITY: HIGH) For very large CROME systems i.e. four or more OMCs or OMCRs an internal bug in the 1.1.7B JVM will generate an abort via a 16-bit hash table overflow. This problem was corrected in Sun's 1.1.8_001 release.

(FUNCTIONALITY: LIMITED) Very old (Java-1) JRE versions such as the 1.1.8 JRE will still work however CROME will automatically disable some of CROME's more recent advanced features. In additon Java-1 releases will typically run up to 40% slower than Java-2 releases.

Java 1, SUN JRE/JDK 1.1.8 - approved, no longer recommended

No known issues that have not been solved by Quantum.

Current rev Solaris 1.1.8_10 and 1.1.8_14, Windows 1.1.8_008.

Note, the native threads version i.e. Solaris production release of 1.1.8_14 provides much better performance over the Solaris 1.1.8_10 release.

(FUNCTIONALITY: LIMITED) Very old (Java-1) JRE versions such as the 1.1.8 JRE will still work however CROME will automatically disable some of CROME's more recent advanced features. In additon Java-1 releases will typically run up to 40% slower than Java-2 releases.

(EOL: INFORMATION) Sun Microsystems has End-of-Lifed this release of Java (e.g. Java-1) if you must run a Java-1 varient this is the proper release.


Java 2, SUN JRE/JDK 1.2.1 - not recommend

(CRITICALITY: LOW) Timezones have changed for example Pacific Standard Time prior to 1.1.8 is now America/Los_Angeles. This is not a BUG but an API change that requires regression testing.

(CRITICALITY: HIGH) The AWT queue deadlocks under Win95 and Win98 if run in 16bit color resulting in a machine crash - the work around is use 24bit or 32bit color or even 8bit color. Sun JDK bugs: 4211948 and 4212051.

(CRITICALITY: HIGH) Win95/98/NT read an incorrect creation time from files made in a different daylight savings zone. New code under test has fixed this issue, will prevent NetworkUpdate from functioning. Sun JDK bug(s): 4242143 4077832 (prematuraly closed).

(FUNCTIONALITY: LIMITED) This release of (Java-2) JRE will still work however CROME will automatically disable some of CROME's advanced features such as Graphics-2D and Scripting.


Java 2, SUN JRE/JDK 1.2.2 - not recommend

(PERFORMANCE: N/A) Finally Sun has supplied the promised performance this is only slightly slower than IBM 1.1.7B and 1.1.8 which makes it the second fastest JVM we have seen to date.

(CRITICALITY: LOW) Timezones have changed for example Pacific Standard Time prior to 1.1.8 is now America/Los_Angeles.

(FUNCTIONALITY: LIMITED) This release of (Java-2) JRE will still work however CROME will automatically disable some of CROME's advanced features such as Graphics-2D and Scripting.


Java 2, SUN JRE/JDK 1.3 standard - approved, but 1.4.2 preferred

(PERFORMANCE: N/A) Performance is on par with the IBM 1.1.7B and 1.1.8 JVMs.

No known issues that have not been solved by Quantum.


Java 2, SUN JRE/JDK 1.3.1 standard - approved, but 1.4.2 preferred

(PERFORMANCE: N/A) Performance is much better than the IBM 1.1.7B and 1.1.8 JVMs, especially with large data sets.

No known issues that have not been solved by Quantum.


Java 2, SUN JRE/JDK 1.4.2 standard - approved, currently recommended as of 7/25/2006

(PERFORMANCE: N/A) Performance is the best to date.

(STABAILITY: N/A) High Stability.

No known issues that have not been solved by Quantum.


Java 2, SUN JRE/JDK 1.5.0 standard - approved, also recommended as of 7/25/2006

(PERFORMANCE: N/A) Performance is on par with JRE/JDK 1.4.2 the first recomended release is 1.5.0_07 across all platforms (Win95/98/NT/ME/2000/XP or Solaris X86)

(STABAILITY: N/A) High Stability.

No known issues that have not been solved by Quantum.


Other JVMs and platforms

QuantumSI continously verifies and validates performance and functional from many vendors and VM releases. Although CROME will run on other operating systems such as HPUX or LINUX and even beta releases of JVMs from Sun (i.e. Mustang 1.6 which is currentlky in beta2) we only provide active support for either a) Sparc client machines (running Solaris), and b) X86 client machines (running Win95/98/NT/ME/2000/XP or Solaris X86).
