Ivo Ladage - van Doorn commented on AMDATU-319:
-----------------------------------------------
Its a timing issue. Cassandra adds a JVM shutdown hook and shuts down Cassandra
when it receives the shutdown event. Now asynchronously, the Felix framework
shuts down and so stops the Cassandra daemon bundle and destroys the bundle
classloader. Now when that happens first, the Cassandra shutdown thread access
cassandra classes loaded by the bundle class loader which has been destroyed in
the meantime.
So what should be done is implementing a wait in the daemonservice stop method,
ensuring that the cassandra shutdown thread terminated before the bundle is
stopped.
