[jira] Updated: (DERBY-1694) derbynet/testProperties.java hangs
[ http://issues.apache.org/jira/browse/DERBY-1694?page=all ]
Mike Matrigali updated DERBY-1694:
----------------------------------
I have not seen this test fail since I increased the timeout as part of DERBY-1810. Is this test still failing for anyone since then?
In a little debugging of this I think the problem might be related to OS port resources being freed from the previous startup/shutdown of the network server on the default port 1527.
There is definitely as separate test issue here, in that once the connect fails the test hangs - but I believe that is purely a test issue and not a product issue. At least for me tests now run so I would not hold up 10.2 for this issue.

> The testProperties.execCmd() is used to fork a JVM and not handle its
> streams. This will cause problems, as indicated by the javadoc for Process.
> "The parent process uses these streams to feed input to and get output
> from the subprocess. Because some native platforms only provide limited
> buffer size for standard input and output streams, failure to promptly
> write the input stream or read the output stream of the subprocess may
> cause the subprocess to block, and even deadlock"
