Strange, looks like there was no Preferences instance in MimeLookup.

Comment 5 Vitezslav Stejskal 2009-04-20 13:19:04 UTC 
The root cause is:

java.util.ConcurrentModificationException
	at java.util.HashMap$HashIterator.nextEntry(HashMap.java:841)
	at java.util.HashMap$EntryIterator.next(HashMap.java:883)
	at java.util.HashMap$EntryIterator.next(HashMap.java:881)
	at org.netbeans.core.startup.NbInstaller.shouldDelegateClasspathResource(NbInstaller.java:829)

I'm going to attach the whole stacktrace from messages.log.
