* java/lang/PosixProcess.java (exitValue): Implement here. Throw IllegalThreadStateException if process hasn't exited yet. * java/lang/natPosixProcess.cc (exitValue): Removed. (waitFor): Only check thread interrupted status if waitpid() returned an error. Use WIFEXITED and WEXITSTATUS to process process's exit value. From-SVN: r45766
