PI69028: Null CodeSource location for classes loaded by JSPExtensionClass Loader

Fixes are available

APAR status

Closed as program error.

Error description

When a class is loaded by the JSPExtensionClassLoader
(typically, these classes are generated from JSPs or tag
libraries), the code source location on the class's
ProtectionDomain is set to null.  This can make it hard for
debugging classloader issues.
