File.deleteOnExit() Java API call causes JVM crashes on long running servers

Summary

The File.deleteOnExit API is flawed and causes JVM crashes on long running servers. See http://bugs.java.com/view_bug.do?bug_id=4513817 :

Every time I use "ImageIO.write(img, "png", outStream)" a temporary file is
created, and the "deleteOnExit()" function is called on that temporary file.
Every "deleteOnExit()" allocates a "struct dlEntry" in the shared "io_util.c"
native source file. This "struct dlEntry" is about 1K in size, and will never be
freed until the system exits, so every time I do an ImageIO.write() I take up
another 1K of memory!

Notes

• This will only affect long running servers

Workaround

• Restart server Confluence is running on occasionally
