[infinispan-dev] parked task?

[Sanne Grinovero]

The thread waiting on:
at org.hibernate.search.backend.impl.lucene.LuceneBackendQueueProcessor.applyWork(LuceneBackendQueueProcessor.java:97)
is legit, it needs to wait on the Infinispan cache to be available to
complete the write operations on the index, which writes on the
Infinispan caches.

I think this is basically the same problem as the other problem you reported.
