Maxim Muzafarov commented on CASSANDRA-18423:
---------------------------------------------
I think I need to share some intermediate results as I have spent a few days
investigating the cause.
- I can confirm the issue, but the scope is a bit wider. In fact, all the
tests with the {{.jdk11}} postfix are not run as they are stuck on the first
one {{testLargeIndexSummary}} with an error {{{}Forked Java VM exited
abnormally.{}}}.
- I have failed to reproduce the issue locally using the {{testclasslist}}
build step (or I also tried creating a new ant target to emulate the
environment);
- There are no logs for the failed suite on Jenkins (see the link), so it is
difficult to find out the cause of failed tests. The error {{Forked Java VM
exited abnormally.}} is just the tip of the iceberg, the real cause is hidden
and alive in the agent logs (I have no access to them);
[https://nightlies.apache.org/cassandra/devbranch/Cassandra-devbranch/]
I have reproduced the same stack trace limiting the maximum heap size on the
local JVM running the tests just to be sure of the possibility of such a
scenario. The easiest way to find the real cause is to find the full log or
fetch it from the build agent. I'll continue the investigation.
