The Object.wait() method should ALWAYS be called from within a loop (checking a conditional variable) to protect from "spurious wakeup." This has always been the case, and 4308396 (committed to tiger) plans to make this very clear in the Object.wait() documentation.

While looking at the source for java.awt.EventQueue I discovered at least one usage of wait() outside of any loop. This usage occurs in the method invokeAndWait(). That call to wait() should be wrapped in a loop that checks a variable, rather than assuming that it IS time to wake up.

Also, there are a couple of other wait() calls in EventQueue that should be double checked to ensure they follow the rules.
