Comment 4 for bug 897013

I have freshly installed Ubuntu 12.04 LTS on a PC with 6GB of RAM.
 I then installed Eclipse Indigo and then the CDT addon.

 When I start the Eclipse-CDT IDE it immediately crashes with the following message:

 'Project Explorer' has encountered a problem
 An internal error has occured
 Java heap space

 Here is the log...

 Here is the session data...

 java.version=1.7.0_03
 java.vendor=Oracle Corporation
 BootLoader constants: OS=linux, ARCH=x86, WS=gtk, NL=en_GB
 Command-line arguments: -os linux -ws gtk -arch x86

 I have tried increasing the Java Heap space, but this did not help.
 I even tried a upgrading the Java version to 1.7, but there was no improvement.

 Here is the contents of my /etc/eclipse.ini file

 -startup
 plugins/org.eclipse.equinox.launcher_1.2.0.dist.jar
 --launcher.library
 plugins/org.eclipse.equinox.launcher.gtk.linux.x86_1.1.100.dist

 NB: Whilst this may be a red-herring, I access this headless PC using VNC.

 NB: I also see the following error in the logs...
