Andrei Dulceanu commented on OAK-4735:
--------------------------------------
Per [~frm]'s latest discovery
{{DataStoreTestBase.testProxyFlippedIntermediateByteChange2}} invoked from
{{ExternalPrivateStoreIT}} seems to be stuck forever in the client waiting for
the connection to close:
{code:java}
"main" #1 prio=5 os_prio=31 tid=0x00007fb913806800 nid=0x1703 in Object.wait()

{code}
the monitor is acquired by these lines in {{StandbyClient}}:
{code:java}
try {
long startTimestamp = System.currentTimeMillis();
// Start the client.
ChannelFuture f = b.connect(host, port).sync();
// Wait until the connection is closed.
f.channel().closeFuture().sync();
this.failedRequests = 0;
this.syncStartTimestamp = startTimestamp;
this.syncEndTimestamp = System.currentTimeMillis();
this.lastSuccessfulRequest = syncEndTimestamp / 1000;
} catch (Exception e) {
this.failedRequests++;
log.error("Failed synchronizing state.", e);
} finally {
synchronized (this.sync) {
this.active = false;
shutdownNetty();
}
}
{code}
