Description Jesse Glick 2010-07-27 23:00:14 UTC 
BuildImplTest.testJavadocPackagesDocumented failed due to an uncaught runtime exception manipulating progress handles:

java.lang.ArrayIndexOutOfBoundsException: 0 >= 0
	at java.util.Vector.elementAt(Vector.java:427)

Looks to me like TaskModel reads & writes the 'model' field without apparent synchronization. Not sure if the InternalHandle lock is supposed to control all accesses.
