About the Error occurred while uninstalling Eclipse plugins

When I try to install some plugins for my eclipse, there always some error like:

An error occurred while uninstalling
session context was:(profile=epp.package.java,
phase=org.eclipse.equinox.internal.provisional.p2.engine.phases.Uninstall,
operand=[R]org.apache.commons.lang 2.3.0.v200803061910 –>
[R]org.apache.commons.lang 2.3.0.v201005080501,
action=org.eclipse.equinox.internal.p2.touchpoint.eclipse.actions.UninstallBundleAction).
Error while loading manipulator.
Error while loading manipulator.

At first, I think maybe it’s because my proxy set up. but after try my times, I think maybe because my eclipse has been changed.
So I download a pure eclipse, and I can install the plugins now.

Then I check the config file of Eclipse(eclipse.ini), it has been modifed, and just few paramerters like: xms, xmx…I think it’s just because the config. and here is a bug page:https://bugs.eclipse.org/bugs/show_bug.cgi?id=325757(some one think it’s a bug)

And my solution is:
Check your eclipse config file(eclipse.ini), make sure it’s correct, see: http://wiki.eclipse.org/FAQ_How_do_I_increase_the_heap_size_available_to_Eclipse%3F
