Michiel Toneman commented on WW-4027:
-------------------------------------
Please be careful with the current version of Commons OGNL. We tried to migrate
to commons-ognl to work around the broken 3.0.6 version packaged with Struts2
2.3.15.1 (see https://issues.apache.org/jira/browse/WW-4113) and we ran into a
blocker:
The DefaultClassResolver uses the following code to resolve classes:
ClassLoader classLoader = ClassLoader.getSystemClassLoader();
try
{
result = classLoader.loadClass( className );
}
We stopped trying to get it to work at that point. I fail to see how that would
work in a Tomcat environment with mutiple classloaders.

> OGNL 3 was moved under ASF umbrella and right now it is a part of Commons
