Hi Dmitry, I was able to create a demo to reproduce it. It seems that the issue is triggered by Windows#setEnabled(boolean).
Steps to reproduce it with attached WindowTest.java, maybe you need 2-3 attempts: (0. start the demo program) 1. click on the button in the first window ; a second window opens 2. click on the button in the second dialog ; a third windows open 3. move the third window via mouse and click on the label 4. wait 9 seconds ; a fourth windows is opened (the fourth windows should be opened behind the third) 5. try to close the fourth -> EDT is blocked Attached threads_report.txt is a full thread dump after step 5. FYI: I just re-checked the logs, the original integration test was never run on macOS with a older JDK 9. The original integration passes with: - JDK 8 u152 EA on Windows and macOS - JDK 9 b157 EA on Windows ; macOS not tested - JDK 9 b159 EA on Windows ; hangs on macOS as described Thanks Reto > -----Ursprüngliche Nachricht----- > Von: dmitry markov [mailto:dmitry.mar...@oracle.com] > Gesendet: Donnerstag, 9.
