[jboss-dev-forums] [Design of Security on JBoss] - JBAS-7049: AccessController permission check throwing NPE

[anil.saldhana@jboss.com]

Looks like an OpenJDK6 issue where the permission check for getParent of a classloader is failing with an NPE because probably the parent class loader is null (boot CL).

Any second thoughts?

This is only on openjdk6 and not on Sun JDK6.
