Bug 380631

Description Nicholas Lee 2012-05-25 05:44:12 EDT

The problem occurs when remotely accessing an Ubuntu 12.04 LTS PC from another PC and the "clipboard transfers" option is enabled in the VNC.
The only application to exhibit the problem seems to be Eclipse CDT, which fails on startup with a Java Heap out of memory error.
If I disable the "clipboard transfers" VNC option then Eclipse CDT starts normally.
Increasing the size of the Java Heap space settings in eclipse.ini has NO effect on this problem.
The target machine has 6GB of memory, so it has plenty to play with.

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.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

 --launcher.library
 plugins/org.eclipse.equinox.launcher.gtk.linux.x86_1.1.100.dist

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