Bug 1219: IOUtil.testDirExe: Satisfactory when executed, more debug options IOUtil.testDirExe(): - Satisfactory when executed Failure to execute produce an IOException right at ProcessBuilder.start(). Hence we can allow an unexpected process exit value, since we only want to learn whether executable files are allowed. - More debug options DEBUG_EXE: 'jogamp.debug.IOUtil.Exe' DEBUG_EXE_NOSTREAM: 'jogamp.debug.IOUtil.Exe.NoStream' - if DEBUG_EXE - a pre-existing 'jogamp_exe_tst'+<SUFFIX> will be used as-is. - the test-exe will not be deleted - StreamMonitor is being used to dump stdout/stderr if !DEBUG_EXE_NOSTREAM.
Bug 1219: Fix IOUtil.StreamMonitor EOS handling - Make StreamMonitor a daemon thread, i.e. not hindering VM from exit - Earmark each InputStream's EOS state and only attempt to readByte if !eos - End loop and hence the thread if all InputStream have reached EOS. - Don't close the InputStream. Closing the InputStream is expected to be done by the owner, otherwise no EOS could even be reached! - Flush the output PrintStream at thread exit
