XEclipse does not start on OSX if JDK 1.6 is selected

Unfortunately, one still need to tweak the Info.plist in order for XEclipse to start on OSX 10.5 with JDK 1.6 set as preferred JDK.
The tweaks involve setting a vm version as explained in the plist.

replace:

<!-- to use a specific Java version (instead of the platform's default) uncomment one of the following options:
<string>-vm</string><string>/System/Library/Frameworks/JavaVM.framework/Versions/1.4.2/Commands/java</string>
<string>-vm</string><string>/System/Library/Frameworks/JavaVM.framework/Versions/1.5.0/Commands/java</string>
-->

with

<string>-vm</string><string>/System/Library/Frameworks/JavaVM.framework/Versions/1.5.0/Commands/java</string>

I would recommend to do this change now since the binaries are 32 bits only and no further java on MacOSX will be released for 32 bits anyways (see java-dev mailing-list).
