14010 - Are JAVA 2 JVMs supported?

Status: VERIFIED FIXED

(Core Graveyard :: Java: OJI, defect, P3)

Description

[dmgaskin]

Overview
========
   JVM (Java Virtual Machine) requirements are not stated (at least I couldn`t
   initially find it). As a serious Java developer I have:
      Javasoft JDK 1.1.8,
      Javasoft JAVA SDK 2 1.3 beta
      Microsoft's Java SDK 3.2
   on each of my Windows boxes an for my development I change the path to
   switch between JDK 1.1.x and JAVA 2 and use the different names for MS Java
   (ie javac -> jvc and java -> jview etc.).
   I hate the Windows Registery and do not depend on it at all.

   When apprunner is started (irrerspective of the active PATH environment
   variable) it brings the following protocoll
   ============== START OF PROTOCOLL ==================
C:\sw\mozilla>bin\apprunner
Profile Manager : Command Line Options : Begin
Profile Manager : Command Line Options : End
Profile Manager : Profile Wizard and Manager activites : Begin
Profile Manager : Profile Wizard and Manager activites : End
Java(TM) HotSpot Client VM warning: Setting of property "java.compiler" is ignored
Proxy-Konfiguration:Browser Proxy Configuration

initialization error: Can't load class netscape/javascript/JSUtil
initialization error: Can't read static field java.lang.Void.TYPE
Toolbar registered as Drag Listener

Doing Startup...
Creating browser app core
BrowserAppCore has been created.
Setting content window
browser.startup.page = 0
startpage = about:blank
JavaScript error: Package java defined twice ?
   ============== END   OF PROTOCOLL ==================

   Java(TM) HotSpot exists only for JAVA 2 therefore it would appear that
   Mozilla uses the Windows registery to find an installed JVM.

   Does Mozilla work on with JAVA 2 (any version)?
   PLEASE ANSWER THE ABOVE QUESTION as I have lots of problems with Mozilla but
   if it is not designed to run on JAVA 2 there is no point in me submitting
   large numbers of bug reports.

Steps to reproduce
==================
   Install JAVA 2 (if not already available) and start apprunner
Actual Result
==============
   See protocol above.
Expected Result
===============
   No errors in startup

Strictly speaking, any Java VM that can support the OJI API's will be supported.
In practice, however, there are only a few Java VM Plug-In's currently
implemented: the Apple MRJ Plug-In, which is essentially JDK 1.1.8, and Sun's
own Java Plug-In, the latest version of which is JDK 1.3 Beta, and is available
on Win32 and Solaris.  Since Mozilla API's are in rapid flux, it is difficult
for vendors to keep their plugin implementations in place.  However, you should
be able to use the Sun 1.3 Beta JVM with current Mozilla builds.  Keep in mind
that there is a bug in the HotSpot module that prevents its use with Mozilla;
this bug has been filed with Sun and will be fixed by the time JDK 1.3 FCS is
available.  To use the 1.3 JDK with Mozilla, simply find your "hotspot"
directory and rename it to anything else (the "hotspot" directory should be in
"jre\bin\hotspot" whereever your JDK is installed).
