[jboss-remoting-issues] [JBoss JIRA] Commented: (JBREM-1184) Fix NPE in ClassByteClassLoader.addClass()

[Ron Sigal (JIRA)]

    [ https://jira.jboss.org/jira/browse/JBREM-1184?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12514511#action_12514511 ] 

Ron Sigal commented on JBREM-1184:
----------------------------------

ClassByteClassLoader.loadFromNetwork() tests if the returned ClassBytes object holds a null class.

Testing:  It's difficult to test for the NPE since it is logged but not rethrown: a ClassNotFoundException is thrown if the class is never found.  However, the test class org.jboss.test.remoting.classloader.RemoteClassloaderTestCase has been committed to document the problem.  The RemoteClassloaderTestCase.testClassNotFound() passes even in the event of a NPE, but the NPE should not be seen in the log file.

Waiting for results in hudson.;

> When org.jboss.remoting.marshal.MarshallerLoaderHandler gets a request for a class, it returns an instance of org.jboss.remoting.loading.ClassBytes.  If MarshallerLoaderHandler isn't able to find the desired class, then the returned ClassBytes object has null value for the class byte array.  However, org.jboss.remoting.loading.ClassByteClassLoader doesn't check for the possibility of a null byte array.
