[eclipse-dev] Deadlock while running JDT UI JUnit tests on Linux for I20

[Sonia Dimitrov <Sonia_Dimitrov@xxxxxxxxxx>]

It appears that a deadlock occurred
while running the JDT UI JUnit tests on Linux only for build I20031126
(0800).  See thread dump below.

The remaining tests are completing,
results should be available later today.
