I have configured the Froyo source code in eclipse. I am trying to run
android junit test "Run as-> Android JUnit Test", a error pop-up
comes.
When i try to run the already existing Android Junit Test cases or my
own test case (compiled with froyo source), I get following error.
Test runs fine when I run it from command prompt.

I guess this is ADT related issue, but don't have any solution. I
tried it on Eclipse galileo and helios, tried ADT 8.0.. and 9.0.0,
Java version 1.5 and 1.6...nothing worked.

Please help


Message that i get is:

Problems occurred when invoking code from plug-in:
"org.eclipse.jface".

And the log shows:
