Which vm is really running? [message #244210]

I have a few JDKs (1.4,1.5,1.6) installed and I'm trying to tell eclipse
(3.3) to run on the 1.5 version. I put the -vm in my Eclipse.ini file as
this:

**ECLIPSE.INI
-clean
-showsplash
com.genuitec.myeclipse.product
--launcher.XXMaxPermSize
256m
-vm C:\DevTools\Java\1.5.0_12\bin
-vmargs
-Xms512m
-Xmx512m
-Dosgi.splashLocation=C:\DevTools\MyEclipse\eclipse\MyEclips eSplash.bmp
-Duser.language=en
-XX:PermSize=512M
-XX:MaxPermSize=512M

I see in the IDE that its picking up the memory args (though it reads 508M
max), but when I look at the config info I see this (among other things):

(...)
-clean
-vm C:\DevTools\Java\1.5.0_12\bin
-vm
C:\Program Files\Java\jre1.6.0_03\bin\client\jvm.dll
(...)
eclipse.vm=C:\Program Files\Java\jre1.6.0_03\bin\client\jvm.dll
eclipse.vmargs=-Xms512m
-Xmx512m
-Dosgi.splashLocation=C:\DevTools\MyEclipse\eclipse\MyEclips eSplash.bmp
-Duser.language=en
-XX:PermSize=512M
-XX:MaxPermSize=512M
(...)
java.home=C:\Program Files\Java\jre1.6.0_03

java.runtime.name=Java(TM) SE Runtime Environment
java.runtime.version=1.6.0_03-b05
java.specification.name=Java Platform API Specification
java.specification.vendor=Sun Microsystems Inc.
java.specification.version=1.6
java.vendor=Sun Microsystems Inc.
java.vendor.url=http://java.sun.com/
java.vendor.url.bug=http://java.sun.com/cgi-bin/bugreport.cgi
java.version=1.6.0_03

java.vm.name=Java HotSpot(TM) Client VM
java.vm.specification.name=Java Virtual Machine Specification
java.vm.specification.vendor=Sun Microsystems Inc.
java.vm.specification.version=1.0
java.vm.vendor=Sun Microsystems Inc.
java.vm.version=1.6.0_03-b05
(...)

My PATH is set as:
D:\databases\Oracle10g\home\bin;%SystemRoot%\system32;%Syste mRoot%;%SystemRoot%\System32\Wbem;C:\Program
Files\ATI Technologies\ATI Control Panel;C:\Program
Files\QuickTime\QTSystem\;c:\Program Files\Microsoft SQL
Server\80\Tools\Binn\;c:\Program Files\Microsoft SQL
Server\90\Tools\binn\;C:\Program Files\Java\jre1.5.0_12\bin;C:\Program
Files\ATI Technologies\ATI.ACE\

My JAVA_HOME is:
C:\Program Files\Java\jre1.5.0_12

My CLASSPATH is:
;C:\Program Files\Java\jre1.6.0_02\lib\ext\QTJava.zip

Any idea how to tell what's really running? How can I make sure that its
only running 1.5, but keep the 1.6 JDK around to compile and test against?

Thanks!!

The config info is telling the truth.

I think what's going on is that the whitespace in your -vm line is
invalidating that part of your .ini file, and Eclipse is falling back on the
VM that it finds on the path.

Try doing it like this:

-vm
C:\DevTools\[etc.]
-vmargs
-Xms512m
[etc.]

The -vm argument has to point to the vm executable not the directory
that contains the vm. I believe that you have to break the argument
into two separate lines.

Give this a try:
-vm
C:\DevTools\Java\1.5.0_12\bin\javaw.exe
