Description Jesse Glick 2008-10-03 21:59:54 UTC
java.lang.IllegalThreadStateException: You are attempting to make changes to org.netbeans.ModuleManager@a2220f in a
property change callback. This is illegal. You may only make module system changes while holding a write mutex and not
inside a change callback. See #16328.
	at org.netbeans.ModuleManager.assertWritable(ModuleManager.java:226)
	at org.netbeans.ModuleManager.disable(ModuleManager.java:932)
	at org.netbeans.api.autoupdate.OperationSupport.doOperation(OperationSupport.java:67)

Indeed MM is being used without taking a lock first, contrary to its documentation.
