If by Toolkit thread you mean the thread that is responsible for
obtaining and dispatching platform events, then no, you can't use
invokeLater here. The more general rule is that you can't use
invokeLater in the main thread group (to which Toolkit thread belongs to).

Hi, Leonid.
Does it mean that we cannot use InvokeAndW/Later on the toolkit thread?

Hi,
Please review a fix for 8014264: The applet pathguy_TimeDead throws
java.lang.NullPointerException in java console once click drop-down
check box.
The problem here is that for applets prePostEvent is called within
ThreadGroup that, by design, has no AppContext associated with it.
So, when the code in XChoicePeer/XListPeer prePostEvent
implementation calls EventQueue.invokeLater, it results in NPE
because there is no EQ for this ThreadGroup.
The fix is not to use invokeLater, but to manually create
InvocationEvent to ensure that target's AppContext would be used to
find an EQ for the event to go into.
