Re: [keycloak-dev] no stack trace in testsuite failed run
I've just had similar (or probably same) issue in ComponentsTest.
TestCleanup class was using thread-unsafe LinkedList under the covers.
So some concurrency tests had issues, as they updated LinkedList from
more threads and then this NPE can happen when iterating through LinkedList:
java.lang.NullPointerException
at java.util.LinkedList$ListItr.next(LinkedList.java:893)
at
org.keycloak.testsuite.util.TestCleanup.executeCleanup(TestCleanup.java:143)
at
org.keycloak.testsuite.AbstractKeycloakTest.afterAbstractKeycloakTest(AbstractKeycloakTest.java:178)
When this happened, I saw the other test methods fail with empty NPE
like for you.
I've fixed it in latest master by making the class TestCleanup
thread-safe. Hopefully this will fix your issue too. Sorry for troubles
as thread-unsafe TestCleanup was my fault :(
BTV. Some concurrency tests like BruteForceTest or ComponentsTest still
have issues because of H2 locks. I can sometimes simulate on my laptop
and seeing that they sometime fails on travis too. But that's separate
issue and hopefully it's just specific to H2.

My test is failing in AbstractKeycloakTest.afterAbstractKeycloakTest
while running TestCleanup loop. I'm getting a NullPointerException but
I can't seem to get the testsuite to output the stack trace. I do see
info level logs from this class, but no stack trace. Even if I add a
exception.printStackTrace(). The stack trace is empty.
Any ideas? This popped up before but just magically disappeared. Now
its back. The test failure only comes up in a full maven build. Can't
reproduce in IDE.
Thanks,
Bill
