This problem is side effect of issue 193 (https://glassfish.dev.java.net/issues/show_bug.cgi?id=193) and is described in details in issue 634 (https://glassfish.dev.java.net/issues/show_bug.cgi?id=634). Your choices are to use the work around described in the above issue or switch to the GlassFish build with the fix.
