This pagehandler can cont ain references to more data. Workaround: None
Local fix
Problem summary
When storing EGL data in a J2EE session, references to other portions of the Java runtime were preventing garbage collection of those objects. This could potentially cause an OutOfMemoryError.
Problem conclusion
The implementation has been changed to no longer store these references in the session map, greatly reducing the memory usage.
Temporary fix
