Tomcat -> GlassFish: Changes to default-xml at runtime

Problem:
In Tomcat 6, changes to the "default" web.xml take effect on server restart with requiring applications to be deployed. But in GlassFish v2, changes to the default-web.xml requires applications to be redeployed even after a restart. This is caused by issue https://github.com/javaee/glassfish/issues/3844

Solution:
The issue https://github.com/javaee/glassfish/issues/3844 has been fixed in GlassFish V2.1.
