most of the reports have low Xmx: 300, 400 or 700MB while the NB default is 1024Mb. 
The only relevant report is http://statistics.netbeans.org/exceptions/exception.do?id=759310: a HashMap of over 8 million entries (HM#91686) is held by 
vm (Java frame)	JPDAThreadImpl	vm (Java frame)
target	VirtualMachineImpl	target
waitingQueue	TargetVM	waitingQueue
