Description Petr Pisl 2013-01-10 10:06:21 UTC 
Some times the ide crash with OOM Exception. From the thread dump it's clear that resolving prototype chain can be never ending:

at org.netbeans.modules.javascript2.editor.model.impl.ModelUtils.findPrototypeChain(ModelUtils.java:838)
	at org.netbeans.modules.javascript2.editor.model.impl.ModelUtils.findPrototypeChain(ModelUtils.java:838)
.....

Still the same line.
