Running GWTTestCase in Netbeans IDE and "Java heap space" error

Hi List!

I use Netbeans 6.7.1 and GWT 1.7.

I already tried to find if this problem has been reported before and
indeed found one
thread which I mention below.

The problem is that within my Netbeans IDE I simply cannot run *any*
GWTTestCase
because there is always a "java.lang.OutOfMemoryError: Java heap
space" error
(see below for error message).

I already tried to fix this by allocating more memory but it didn't
help.

The problem seems to have been reported back in July last year:

http://groups.google.com/group/google-web-toolkit/browse_thread/thread/b831a71efc4382d2/

Ironically, while being not able to run any GWTTestCase in Netbeans
(standard JUnit
tests all work), I immediately succeeded running one GWTTestCase in a
different
application with Eclipse and the Google GWT Plugin. So I checked, but
could not find
any differences between both projects concerning the compiling process
and the
tests. In fact, I even got the same "Java heap space" error within
Eclipse as I used
"Run As... JUnit Test" within the Eclipse context menu - if I use the
"correct"
"Run As... GWT JUnit Test" (which is provided by the Google GWT
Plugin, I think) any
GWTTestCase in Eclipse works.

Does this indicate anything that helps to solve my problem? What can
be the difference
between those two options in Eclipse and what happens if I choose one
or the other?

Many thanks in advance and regards,

Daniel
