increasing maximum heap size to 1024m in eclipse.ini is being ignored ...

[Wayne Johnson]

OS: W7
Scala plugin version: 2.0.0.beta07-29-201106291626-94328fa
Eclipse version: 3.7.0.v201106131736 (JEE download x86-64)

The scala update diagnostics recommends a maximum heap size of at least 1024. I made changes to the eclipse.ini in the installation directory but the settings are not reflected in the configuration report (Help>About Eclipse>Installation Details>Configuration). This is not a Scala-IDE issue, but I've spent much of the day in Eclipse and Equinox trying to track down why the VM args are overridden and have found nothing. Help would be appreciated.
(Also tried running eclipse.exe -clean from a cygwin window.)

From the Eclipse IDE, how did you determine this?

When I add the arguments on the command line (eclipse.exe -vm ...),
the configuration report matches the values used on the command line
(as expected) but does not use the values in eclipse.ini if command
line arguments are not present. What is injecting the values I see in
the report and what is the source for these values?

Eclipse.ini

-vm
C:\Program Files\Java\jre6\bin\server\jvm.dll
-vmargs
-Dosgi.requiredJavaVersion=1.5
-Xms256m
-Xmx1024m

Config report

eclipse.vm=C:\Windows\system32\javaw.exe
eclipse.vmargs=-Dosgi.requiredJavaVersion=1.5
-Xms40m
-Xmx512m
