> With a big of digging I was able to reliably reproduce it by using {{-Dtests.dups=N}} (which normally runs in multiple JVMs in parallel) together with {{-Dtests.jvms=1}} constraint so that the tests actually run sequentially in one JVM i.e. altogether
> {code}
> ant test -Dtests.dups=10 -Dtests.jvms=1 -Dtestcase=MultiSolrCloudTestCaseTest
> {code}
> The fix is simple i.e. the static {{clusterId2collection}} variable needs to be cleared in @AfterClass as someone ([~janhoy] ?) already mentioned somewhere elsewhere I think.
