Hi, after doing some profiling and analysis I have found that rhino is doing a lot of class loading which often fails. This is coming from NativeJavaPackage.java / getPkgProperty (a lot of ClassNotFoundException exceptions are thrown and catched there). This stems from references in a flow script to Java classes, ...
Although there is a cache this does not prevent a lot of class loading (failing most of the time) for each new request (until the cache is filled anew). The originating call is in ContinuationInterpreter (ScriptRuntime.getProp). I am not sure how a real fix of this problem would look like. Nevertheless, I have made a naive fix for the problem (patch attached) that simply adds a cache to NativeJavaPackage. This resolved the issue for my test scenario and resulted in a great performance increase. When looking at the initial code I think there could be a more elegant solution (that does not need a "secondary" cache). Furthermore, I am not sure if my "quick fix" has side effects or not (e.g. when a huge number of classes is referenced of one and the same package). Has anybody else already encountered this issue and found a different solution? What do you think of my solution? Any other ideas / comments?
