Justin Bertram 1197898232 ARTEMIS-4571 race condition w/TTL impacting in-vm connections
There is a race condition between ConnectionEntry.ttl and
FailureCheckAndFlushThread whereby an in-vm connection may get closed
inadvertently due to a TTL timeout. This is because ConnectionEntry.ttl
is initialized to 60000 and then later set to -1 upon the initial Ping.
If this update happens at *just* the right time in
FailureCheckAndFlushThread then the connection will be closed.

The fix ensures that the ConnectionEntry.ttl is set to -1 for in-vm
connections from the start. It also eliminates the possibility of the
race in FailureCheckAndFlushThread.

This fix is based on static analysis of the code. The timing window is
just too small to contruct a reliable test. The failure has only been
seen in the wild a handful of times.
