            The workaround is to include a context file in the .war file:

            META-INF/context.xml

            The contents of the file should look like this:

            <?xml version="1.0" encoding="UTF-8"?>
            <Context antiJarLocking="true" antiResourceLocking="true">
            </Context>

              I wasn't able to recreate the issue noted above but since it's transient, perhaps there is some variable I'm missing. There is a known issue with hot/re-deploying compat versions of ICEfaces applications to Tomcat on Windows: ICE-5222

              The workaround is to include a context file in the .war file:

              META-INF/context.xml

              The contents of the file should look like this:

              <?xml version="1.0" encoding="UTF-8"?>
              <Context antiJarLocking="true" antiResourceLocking="true">
              </Context>

              We should add this to all the tests we run on Tomcat when the compatibility jars are included and retest.

              Assigning to Mandeep to verify if this is still a problem or not.

              Icefaces2 revision#22166
              The Null pointer exception was seen in 14 test-cases in the last nightly regression test run(without using there workaround).

              Actually, this is the expected behavior. So long as things work correctly when using the workaround configuration, we are okay with this as it is a Tomcat/Windows issue.
