SecurityException when using ClassImposteriser

Hi all,

With both JMock 2.5.1 and 2.6RC1, I'm getting a stack trace when using
ClassImposteriser. The stack trace is included at the end of this
message. Any ideas as to how resolve this issue?

Not sure if it's significant, but I'm running my test with Eclipse. The
JMock JARs are bundled in an Eclipse plugin project on which my test
plugin depends.

Here's the test class:

@RunWith(JMock.class)
public class MigrationStrategyTest {

private final MigrationContext context = new MigrationContext();

private Mockery mockery;

@Before
public void setup() {
mockery = new JUnit4Mockery() {{
setImposteriser(ClassImposteriser.INSTANCE);
}};

// create mock objects
}

@Test
public void delegatesToApplicableRule() {

mockery.checking(new Expectations() {{
// set expectations
}});

// execute
strategy.migrate(original, context);
}
}

Cheers,
Louis.

Re: SecurityException when using ClassImposteriser

Hi all,

I encountered this problem again today. It seems that Eclipse Galileo
bundles JUnit 4.5, which in turn bundles Hamcrest Core 1.1, which does
not contain org.hamcrest.TypeSafeMatcher.

JMock 2.5.1, however, bundles Hamcrest 1.1, with TypeSafeMatcher. The
Eclipse JUnit 4.5 distribution contains signed JARs, and hence the
exception.

The solution is to ensure that any dependencies on JMock JARs occur
before dependencies on JUnit in every plug-in. That way, Hamcrest is
loaded from JMock, not from JUnit.

If you encounter this problem, feel free to send me an email for more
details.

Cheers,
Louis.
