The usual suspects for build failures on Jenkins are ClassDep and ports
in use. Haven't seen any concurrency failures lately.
However I came accross an interesting test failure recently:
https://builds.apache.org/view/M-R/view/River/job/river-PolicySecurityLoaderUrlTests/10/
This error is produced identically by 5 tests in this particular test
run, but I have not been able reproduce it:
[java] -----------------------------------------
[java] com/sun/jini/test/impl/start/ActivateWrapperRegisterBadImplClass.td
[java] Test Failed: Test Failed: com.sun.jini.qa.harness.TestException:
Unexpected Exception; nested exception is:
[java] Problem creating service for net.jini.event.EventMailbox;
nested exception is:
[java] Failed to start the shared nonactivatable group; nested
exception is:
[java] NonActivatableGroupAdmin: Failed to exec the group; nested
exception is:
[java] invalid stream header: 4572726F
[java]
[java] -----------------------------------------
The test suite redirects the System.in System.out streams to communicate
with a subprocess, where the exception occurs.
Interestingly the invalid stream header, when converted from hex to
ascii reads:
Erro
