Here are the ten source files (not diffs) which were altered to reduce memory leaking in uPortal 2.1.5. Mostly the leak fixes made in 2.3.4 were taken and backported, but a couple more files were also identified.
The JA-Sig 2.3.4 mods addressed leaks related to JDBC operations; here only the JDBC operations in 2.1.5 were looked at. This does not eliminate the leaking but does noticeably reduce the slope of the line.
Unfortunately, all of these files were edited in Windows and may have Windows-style line endings.
