RFR: 8315484: java/awt/dnd/RejectDragDropActionTest.java timed out [v2]

[Damon Nguyen]

> This test intermittently fails by timeout. Increasing the timeout alone doesn't solve the failure as it still fails in about 400 runs. Adding another delay and reducing the delay amount to 1000ms. Now, the test passes after 2 sets of 500 repeats on all OS's without a timeout.
