        Description

        There are different versions of SJSXP. One that comes from java.net and the other one from JDK. ZephyrWriterFactory.java(java.net) changes are not there in XMLOutputFactoryImpl.java(JDK6). JAX-WS relies on certain SJSXP features for correctness and performance. However this particular change

        cvs diff -r 1.4 -r 1.5 ZephyrWriterFactory.java

        is not there in JDK6 version. This causes some of the multi-thread tests to fail. Attaching a test case that fails on some machines. But it is easy to see why it fails(see the above diff). The following works with sjsxp from java.net but not with JDK6.
