Description
FULL PRODUCT VERSION :
java version "1.8.0_72"
Java(TM) SE Runtime Environment (build 1.8.0_72-b15)
Java HotSpot(TM) 64-Bit Server VM (build 25.72-b15, mixed mode)

ADDITIONAL OS VERSION INFORMATION :
Mac OS Sierra 10.12.3

A DESCRIPTION OF THE PROBLEM :
Drag And Drop from one Java window to another does not work. 

If an object is dragged from one window to another window via drag and drop, the drag and drop action is not completed. The java application thinks it is still in the drag and drop. If one tries another drag and drop action an exception will be thrown: 'java.awt.dnd.InvalidDnDOperationException: Drag and drop in progress'. 

It is therefore no longer possible to drag and drop objects in this application. The problem occurs always at the transition between the drag source window and the drag target window. Working with the application is still possible. After a restart of the application, Drag And Drop will work again.

Furthermore, the system Dock becomes disabled and does not react to mouse events - it isn't possible to switch to other windows by clicking their Dock icons. Popup menu on the Dock doesn't work either. Switching to other apps with keyboard works fine though. After quitting the application in broken drag mode, the Dock becomes responsive again. 

The Error occurs in: CDragSourceContextPeer.doDragging(long). This is a native method, which is implemented in the JRE. The Callstack of the corresponding thread:

Thread [Thread-29]
   CDragSourceContextPeer.doDragging(long) line: not available [native method]
   CDragSourceContextPeer.access$100(CDragSourceContextPeer, long) line 49
   CDragSourceContextPeer$1.run() line: 170

This error is similar to the reported error JDK-7177144 but in this case it is a genuine Java application and not netbeans. Maybe the error JDK-7185258 is the reason for this problem.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
A Java appliction with two windows. Drag from one window and drop to the other window. In some cases the drag and drop will not complete successfully. 

To reproduce it is necessary to drag and drop the object multiple times. After that it will occur while dragging the object at the transition from the dragsource window to the dragtarget window.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The dragging should complete successfully.
ACTUAL -
The dragging hangs and drag and drop is no longer possible after the error occurs.

ERROR MESSAGES/STACK TRACES THAT OCCUR :
After the error occurs the next drag and drop will throw the following exception: 'java.awt.dnd.InvalidDnDOperationException: Drag and drop in progress'.

REPRODUCIBILITY :
This bug can be reproduced often.

CUSTOMER SUBMITTED WORKAROUND :
Close the application and restart it. After restart drag and drop works again.
Comments
Checked this with JDK 10 b26 and the issue is still reproducible.

Please recheck this bug on jdk10b23 or later. There are a few related bugs were fixed: JDK-8153871, JDK-8136999 and JDK-8186263.

Reopening this report with added information including test case and results from JDK-8187304. ======================= According to the description, Drag And Drop from one Java window to another does not work. This is a subsequent to JDK-8173803 with a test case. The default expected behavior where the Drag and Drop from one Java window to another does not work, when checked with respective JDK versions (see below). Results (MAC OS X 10.12.5) ================= 8u72: FAIL 8u144: FAIL 8u152 ea b05: FAIL 9 ea b152 b05: FAIL ================

According to Submitter, I will write a little Test application so you can reproduce the issue. I��ll be back to you once I finished it.

Description is incomplete as the testcase created from inputs received from description was unable to reproduce the issue. Recommend provision of a test case to ensure this is an issue by the webbug creator for possibility of triaging this as an issue to be fixed.
