IDEA 4.0.3 build 1182, junit, j2sdk1.5.0beta, NoClassDefFoundError Follow

Hello,

I'm using IDEA build 1182 with java 1.5.0 and junit 3.8.1

JUnit appears not to be working.

I get a ClassDefNotFoundError in com/intellij/rt/execution/junit2/JUnitStarter

I'm not sure what I might be doing wrong. Any help would be appreciated.
