Increased memory consumption in JBoss EAP 5

Issue

• Why does EAP 5 use more memory  than EAP 4.3 or EAP 4.2?
• EAP 5 appears to have a large memory  foot print. Why is this?

• Memory usage comparison of EAP 4.3.0 CP06 vs. EAP  5.0.1:

  EAP 4.3.0_CP06 after startup:
  Heap:  ~200 MB
  PermGen:  ~110 MB
  Accumulated VM size after startup: ~350  MB
  Accumulated VM  size peak during startup: ~600 MB

  EAP  5.0.1 after startup:
  Heap: ~450 MB
  PermGen: ~130 MB
  Accumulated  VM  size after startup: ~750 MB
  Accumulated VM size peak during  startup:  ~1200 MB
