The problem is an omission from a custom classloader in the
WebSphere Application Server J2EE Application access layer.

That custom classloader type uses a delegation model.
During the construction of an instance of the custom
classloader, a reference to a delegate classloader is set --
after -- a call to the superclass step of initializing the
custom classloader.

The superclass initialization performs steps which attempt to
use the reference to the delegate classloader, leading to the
NullPointerException.

The code fix is to check for a null delegate classloader, and to
perform an immediate return if that delegate is null.  An
immediate return will skip a step of initialization of the
delegate, but this is safe because the step is performed by the
delegate when the delegate was created.

The code fix is to a single custom classloader type
"org.eclipse.jst.j2ee.commonarchivecore.internal.util.ArchiveWra
pperClassLoader", which is needed to optimize an initialization
step in that application access layer.

The problem is an omission from a custom classloader in the
WebSphere Application Server J2EE Application access layer.

That custom classloader type uses a delegation model.
During the construction of an instance of the custom
classloader, a reference to a delegate classloader is set --
after -- a call to the superclass step of initializing the
custom classloader.

The superclass initialization performs steps which attempt to
use the reference to the delegate classloader, leading to the
NullPointerException.

Problem conclusion

The code fix is to check for a null delegate classloader, and to
perform an immediate return if that delegate is null.  An
immediate return will skip a step of initialization of the
delegate, but this is safe because the step is performed by the
delegate when the delegate was created.

The code fix is to a single custom classloader type
"org.eclipse.jst.j2ee.commonarchivecore.internal.util.ArchiveWra
pperClassLoader", which is needed to optimize an initialization
step in that application access layer.

The fix for this APAR is currently targeted for inclusion in
fix packs 6.0.2.35, 6.1.0.23, and 7.0.0.3.  Please refer to the
