NPE in JBoss #21

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
When a webapp is reloaded in JBoss, Jboss clears the old webapp
classlaoder, but the classloader and some of its classes may remain available.

A call to a cleared wbapp classlaoder's getURL() throws a NPE.

java.lang.NullPointerException
