When i call the test case below from within eclipse I get this exception with JBoss-5.1.0.GA.
I do not get it with JBoss-5.0.0.GA.

Here's the code:

public class TestPellwormEJB extends TestCase {

public void testSayHello() {
InitialContext ctx = null;
Pellworm tsBean = null;

TestUtils.echoLogHello(this.getClass().getSimpleName(), this.getName());
try

{ ctx = new InitialContext(TestUtils.createInitialContext()); }

catch (NamingException e)

{ fail(e.getMessage()); }
try { // tsBean = (Pellworm) ctx.lookup("PellwormBean/remote"); Object object = ctx.lookup("PellwormBean/remote"); tsBean = (Pellworm) object; } catch (NamingException e) { fail(e.getMessage()); }

try

{ assertEquals("Hallo! Ich bin Pellworm. ", tsBean.sayHello()); }

catch (RemoteException e)

{ fail(e.getMessage()); }

}

}

I haven't found a compatiblity issue in the release notes about this.

Cheers,
-M.
