The java/awt/dnd/DropTargetingTest.java test failed on Windows. Then it timed out, and handling the timeout took 2 hours.

----------System.out:(1/37)----------
Timeout signalled after 240 seconds

JavaTest Message: Test threw exception: java.lang.RuntimeException: Failed to recognize drop on a glass pane

result: Error. Program `C:\...\jdk-17.0.18\bin\java' timed out (timeout set to 240000ms, elapsed time including timeout handling was 7469436ms).


So, there are two problems: the test failed, then it get stuck and couldn't shut down cleanly. The timeout issue is widespread on Windows with drag'n'drop tests.
