Test discovery very slow with JDK11 [message #1805418]

Hi,

we have a project with about 5000 JUnit testcases spread over 700 classes.
When launching the entire test suite in Eclipse 2018-12 with an Openjdk11, the launch takes approximately 60 seconds (which is about as long as the actual test run). It seems to stall on "creating class hierarchy (65%)" in the progress window. We've never seen this until switching over to Java 11. With previous versions of Eclipse and Java 8, this takes about 5 seconds.
I managed to use a JDK8 with 2018-12 as well and then it is fast again, so I don't think the problem lies in Eclipse itself but rather some interaction between Eclipse and JDK11. All this on Windows, I have not tried it in Linux.

All the project's users are seeing the same thing, so it isn't a local problem.

Has anyone else seen this or have a way around it?

TIA,
Chris
