Problem conclusion

If there is no state parameter in the OAuth request, a null is
passed to the URLEncoder.encode method.  Depending on the
JDK, that method may emit a NullPointerException when it
receives a null parameter.

The OAuth provider is updated to not attempt to encode the
state parameter if it does not exist.

When a fix pack containing this APAR is installed, the fix
will not be active until the installed OAuth application,
WebSphereOauth20SP.ear, is updated from the
(WAS_HOME)/installableApps directory.

The fix for this APAR is currently targeted for inclusion in
fix packs 7.0.0.43, 8.0.0.13, 8.5.5.11 and 9.0.0.2.  Please
