One more argument that this issue is caused by synchronization.
{code}
Error Message: expected:<9990> but was:<9989>
{code}
Approximately the same EL was parsed 20000 times, of them 9990 times with an EL error added in the same way, and 10010 times without that EL error. Test detected just one less EL error. It seems most probable, that it was not yet processed when unsynchronized Z.counter was set to zero and check performed too early.
