I've recently discovered on a machine that doesn't have much memory on it that I've got a memory leak. In analyizing the heap dump, the culprate is a java.util.io.DeleteOnExitHook class that contains a LinkedHashMap$Entry class which ultimately contains the string /tmp/jar_cache#######.jar. After running over night, there are a couple million of them.
From what I'm reading... this appears to be a JVM bug located in File.deleteOnExit(), in which the JVM deletes the file, but the record is never purged from the hashmap. I'm wondering, however, if anyone has run into the and has discovered a solution. |

Easiest way would probably be to write a derived class that overrides that method...? or access the source code, fix it and recompile... In any case you may want to open a ticket with the vendor of the JVM and let them know of the problem...
