exec – IllegalThreadStateException: process has not exited
This is one nasty exception I experienced today.
I execute one .executable file from java. Reading the inputstream and the error stream with two different threads (why). I wait till ‘join’ing the thread then I took the process exit value.
processLogThread.join();
errorLogThread.join();
try {
logger.info("Thread status:"+processLogThread.isAlive()+" "+errorLogThread.isAlive());
logger.info("Process exit value:"+p.exitValue());
} catch (Exception e) {
logger.error("Error while reading process exit value", e);
}
Unfortunately, it threw the following exception. The streams are closed. Threads are dead. But it says process has not exited. aaw!!
