JUnit - IllegalArgumentException.class failes?

I have created an extremely simple junit test, which creates a null product in the product table in the db.

@Test(expected = IllegalArgumentException.class)
public void testCreate_NULL() {
    Product p = null;
    createProduct(p);
}

but when I do the junit test it turns blue.

btw. other tests like creating a product, deleting ect. are all green...

I appreciate your answer!!!

PS.: I am using hsql db!

PPS.: The error is:

java.lang.AssertionError: Expected exception: java.lang.IllegalArgumentException at org.junit.internal.runners.statements.ExpectException.evaluate(ExpectException.java:35) at org.junit.internal.runners.statements.RunBefores.evaluate(RunBefores.java:28) at org.junit.internal.runners.statements.RunAfters.evaluate(RunAfters.java:30) at org.junit.runners.ParentRunner.runLeaf(ParentRunner.java:263) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:68) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:47) at org.junit.runners.ParentRunner$3.run(ParentRunner.java:231) at org.junit.runners.ParentRunner$1.schedule(ParentRunner.java:60) at org.junit.runners.ParentRunner.runChildren(ParentRunner.java:229) at org.junit.runners.ParentRunner.access$000(ParentRunner.java:50) at org.junit.runners.ParentRunner$2.evaluate(ParentRunner.java:222) at org.junit.runners.ParentRunner.run(ParentRunner.java:300) at org.eclipse.jdt.internal.junit4.runner.JUnit4TestReference.run(JUnit4TestReference.java:50) at org.eclipse.jdt.internal.junit.runner.TestExecution.run(TestExecution.java:38) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:467) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:683) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.run(RemoteTestRunner.java:390) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRunner.java:197)

UPDATE:

my createProduct Method justs inserts a product into the db and before it checks:

    if(p==null) {
        throw new IllegalArgumentException("null objects impossible");
    }

Perhaps it's throwing NullReferenceException instead of IllegalArgumentException? You should be able to see in the test failure details.

It's fairly hard to diagnose this without any indication of what's in the createProduct method.
