Description Tomas Hurka 2009-04-16 10:45:37 UTC

Opening the heap dump with more than 48,800,000 instances is unnecessary slow on 64bit JVM. 64bit JVM can map LongMap into memory. Current 
implementation fall back to file access if the backing file for LongMap is bigger than Integer.MAX_VALUE.

Fixed in profiler-main
