derbynet/testProperties.java hangs
----------------------------------

                 Key: DERBY-1694
                 URL: http://issues.apache.org/jira/browse/DERBY-1694
             Project: Derby
          Issue Type: Bug
          Components: Test
    Affects Versions: 10.3.0.0
         Environment: Windows XP  IBM 142 JRE
            Reporter: Daniel John Debrunner


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"
