Thread-Dump

While adding a new JDK beside an existing one, I ended up with a deadlock.

- Menu: Window - Preferences - Java - Installed JRE - Add
- Select my JDK Folder
- Press "Apply"

See the attached treaddump!

The "main"-thread and 
"Worker-60: Update Installed JREs" 

are waiting for lock

0x000000070f611540

This is locked by thread "Worker-52: Update Installed JREs"

As default OpenJDK 11 was already in the JRE list. I added JDK8.

After the Eclipse Restart, the JDK8 was successfully added.

It is not reproducable

Comment 3 Andrey Loskutov CLA 2022-02-16 10:01:22 EST 
Most likely was "always" there, not a recent regression, but the fix is trivial, so M3.
Comment 5 Andrey Loskutov CLA 2022-02-16 10:47:52 EST 
Regression from bug 237709 / 4.4. Should be fixed now.
