Issue	Fix Version	Assignee	Priority	Status	Resolution	Resolved In Build

Java applications using signed JAR files will suffer from significant increase of Java heap footprint. The actual jar verification process will also allocated many additional temporary java objects.
The increased memory footprint is caused by the information with the jar manifest and signature files, which is permanently store in the java heap.

Memory footprint seems to be related with length of jar entry names.
