[jboss-dev-forums] [Design of Messaging on JBoss (Messaging/JBoss)] - ClassLoader isolation issue with ObjectMessage
in the trunk, ObjectMessageTest.testClassLoaderIsolation() is failing:
| junit.framework.AssertionFailedError: expected not same
| at
org.jboss.test.messaging.util.ProxyAssertSupport.assertNotSame(ProxyAssertSupport.java:478)
| at
org.jboss.test.messaging.jms.message.ObjectMessageTest.testClassLoaderIsolation(ObjectMessageTest.java:100)
|
The test sends an object message with the normal classloader and receives the message with
another classloader set as the current thread's class loader.
It then checks that the two objects have different classes (since they should belong to 2
different classloaders)
I tried to reuse JBM Stable StreamUtils to unmarshall the object with the right context
class loader but it did not work:
