Steps to reproduce:

1) Enable debug and set break point in PluginContextListener.contextInitialized()

2) Run WabDirTest

Expected: You should not see a folder named "test-portlet' in tomcat-9.0.10/webapps and the break point only be hit once.

Actual: You will see a folder named "test-portlet" in tomcat-9.0.10/webapps, and break point will be hit twice by different threads with same servlet context name "test-portlet".
