the following exception:

1 GB heap space seems enough, so as a workaround, you can set -Xmx1024m in 
eclipse.ini.

• Added labels: Priority-Medium
• Removed labels: Priority-High

[GoogleCodeExporter]

We don't really have control over optimizing heap space, and the workaround 
works fine, so closing.
