jstack output on non-responsive Eclipse

This is the third time I run into a deadlock situation the last months, and I seem to recall it involved auto-complete everytime. Also and perhaps this is accidental I was auto-completing some Java streams code.

Please find to stack traces acquired with `jstack`, taken briefly after one another (one minute between) on the Eclipse instance which wasn't responding any longer. I realize this bug must be very hard to reproduce.

Thanks!

Please try with release 4.9 (2018-09) to see if this is fixed via bug 473654.

Otherwise judging by stack traces this likely is the same as bug 539685.

If you have a reproducing example this would still be welcome (please add it to bug 539685).

Thanks. I've been trying to reproduce the issue but it comes and goes. I'll try the later version as well.
