[infinispan-dev] 9.2 EmbeddedCacheManager blocked at shutdown

I tried our test suite on a slower machine (iMac from 2011). It passes
consistently there.

On my laptop, I keep seeing this from time to time (in different tests):

2018-04-19T19:53:09.513 WARN [Context=org.infinispan.LOCKS]ISPN000320:
After merge (or coordinator change), cache still hasn't recovered a
majority of members and must stay in degraded mode. Current members are
[sombrero-19385], lost members are [sombrero-42917], stable members are
[sombrero-42917, sombrero-19385]

It happens when we shutdown nodes one after the other (even when waiting
for cluster status to be "healthy" plus extra 2 seconds).

After that the nodes remains blocked in DefaultCacheManager.stop
