Minimise erroneous GC pause triggered client disconnections.
Minimise erroneous GC pause triggered client disconnections.

Summary: Set the nailgun client disconnection timeout to 30s, which is above the maximum GC pause time observed with a 2GB heap, and set the target maximum GC pause time to 15s, so that the JVM must miss its target by 100% or many 500ms heartbeats must be missed before a disconnection is triggered.
