JDK-8152974 - AWT hang occurrs when sequenced events arrive out of sequence
Description
After the fix to JDK-8152974 was backported to 8u172,  Java Web Start applications will usually hang when console is opened and focus is switched between application and console.
You can see this running an example from the Tutorial such clicking the launch button on: https://docs.oracle.com/javase/tutorial/uiswing/components/text.html
just run, move application away from console - then resize application and console a few times.

[~kaddepalli] what is a changeset to back out buggy fix?
31-05-2018
Marking this issue as resolved, since the fix has been backed out and JDK-8204142 has been created to investigate the root cause for this behavior.

Created JDK-8204142 to fix JDK-8152974.

Reducing priority, since the changes are backed out in jdk-8u, and a test case is being worked out in jdk11 to test the fix for the problem.

The problem is because of different event ids being posted to the event queue, while the blocked events are expecting a different id. I have a fix for this problem. Working on the testcase.

The problem can also be seen running any applet and resizing the console. The problem goes away when reverting the change in src/share/classes/java/awt/SequencedEvent.java
