gwt, junit SWTException: Invalid thread access on cruisecontrol

[denizstij]

Hi,

I am getting following exception when i run two simple gwt-junit test
cases such as

public void testSimple() {
assertTrue(true);
}

public void testSimple2() {
assertTrue(true);
}

i got following error on CruiseControl (CC):

If i run these tests under eclipse on windows and linux they pass
without any problem. But it fails on CC (which sits on a 64 linux
machine) when i use two or more test cases in same file. However if i
use only one test case on CC, for example only "testSimple", then this
test cases passes too.

Briefly, on cruisecontrol when i tests two or more test cases in a
file, i get above exception.

We are using gwt 1.5 RC1, java 1.5, Junit 4, and cruisecontrol 2.6.2
on a 64 bit linux machine.

Any idea what it would be the problem? Thanks in advance...
