STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Precondition - add debug breakpoint on AWT thread for 2 lines and start the Application in debug mode.
(an object instance of JComboBox.java).addPopupMenuListener(new PopupMenuListener() {
            @Override
            public void popupMenuWillBecomeVisible(PopupMenuEvent e) {

            }

            @Override
            public void popupMenuWillBecomeInvisible(PopupMenuEvent e) {
                loseFilterFocus();// add thread breakpoint 2 here
            }

            @Override
            public void popupMenuCanceled(PopupMenuEvent e) {
                loseFilterFocus();// add thread breakpoint 1 here
            }
        });
2. Press down key which triggers an event to display a modal dialog
3. Intelij idea with debug got focus for breakpoint 1 - press F9
4. Intelij idea with debug got focus for breakpoint 2 - press F9
5. Click somewehere in the application
Repeat from step 2 until AWT freezes. 

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The application is responsive, and we can interact with the modal dialog.
ACTUAL -
The application is not responsive, and we cannot interact with the modal dialog. All other threads beside AWT, are working fine. If any event is posted on the AWT, it will not be processed.

---------- BEGIN SOURCE ----------
Managed to reproduce this only on the production application. If there is not enough info we can try to isolate this in a smaller application. Also if you know more logging that we can enable, in order to investigate this, please let us know,
---------- END SOURCE ----------

CUSTOMER SUBMITTED WORKAROUND :
No workaround. The AWT is not responding at mouse clicks, keyboard events, or other threads are posting on AWT thread some events.

FREQUENCY : often
Comments
Received confirmation from submitter "the issue is fixed with the jdk11 that you provided. Could you please let me know if the fix will be back-ported, and if so, in which java version will it be back-ported"
25-04-2018
Ok, checking with submitter to verify this with current JDK 11 ea build 10.
25-04-2018
Based on the stack trace I assume that this is a duplicate of JDK-8152974. please double check using builds where it was fixed.
25-04-2018
Reported with JDK 8u144, the Java AWT thread freezes when modal dialog is displayed after a keyboard key event. On Windows 10, checked this for reported version as well as subseuquent and could confirm the issue. Results: =========== 8: Fail 8u161: Fail 8u171: Fail 10.0.1: Fail 11 ea b09: Fail To reproduce: - Run the attached test case with respective JDK version. - Select the value Han-ra in the drop down list with mouse or with keyboard until the bug reproduces(AWT thread freezes) Note: The issue occurs randomly. Apparently, while keeping the mouse 1-2 seconds pressed on the Han-ra before releasing the reproducible chances are high. Or, going with over choice - Naouna in the list followed by a press down key. Refer to attached video snippet in subsequent comment for reproducibility.
