As remarked on several places update 21 of 1.6 of the sun oracle jvm doesn’t work well when using lot of perm gem space.
This was caused because oracle changed the vendors name of the jvm to oracle. Because of this eclipse launcher didn’t see it was the sun oracle jvm and didn’t set the –XX:MaxPermSize parameter.
Since 26st of july this issue is solved and oracle released a new version of the jvm. 1.6u21 -b07.
So if you have the problem (only occurs on the windows variants) since you have updated to update 21 then you should update to build 07 (problem occurred in build06)
For more info see this oracle-jvm-6u21-and-eclipse post or the bug

Just installed the new Eclipse 3.6 (Helios) on my Ubuntu. Got some problems with Subclipse saying it could not find the JavaHL libraries (needed for interfacing from Java with Subversion). Problem is that the libraries are installed in /usr/lib/jni and the Eclipse java.library.path doesn’t point to that directory.
How to solve this? Add following line to your eclipse.ini:
-Djava.library.path=/usr/lib/jni/

We must be lucky Terracota sometimes releases new versions of ehcache. This brought up the hidden feature of their automated update checker. Each time you start an application with Ehcache enabled, it makes a connection to the terracotta webserver to check for a new version. This feature is enabled by default!
We don’t need to check this each time, and we don’t want to send info to terracotta each time a developer runs a unit test that has a dependency on ehcache.
to disable it, edit your ehcache.xml:
<?xml version="1.0" encoding="UTF-8"?>
<ehcache updateCheck="false">
...
PS: Quartz also has this feature since version 1.7.2

Google has released a new version of Google spreadsheets for testing.
It looks as if a number of MS Excel UI features have been introduced to make the UI faster to work with.
