### Question:
ProcessImplForWin32 extends Process { static Process start(String username, String password, String[] cmdarray, java.util.Map<String,String> environment, String dir, ProcessBuilderForWin32.Redirect[] redirects, boolean redirectErrorStream) throws IOException { String envblock = ProcessEnvironmentForWin32.toEnvironmentBlock(environment); FileInputStream f0 = null; FileOutputStream f1 = null; FileOutputStream f2 = null; try { long[] stdHandles; if (redirects == null) { stdHandles = new long[] { -1L, -1L, -1L }; } else { stdHandles = new long[3]; if (redirects[0] == ProcessBuilderForWin32.Redirect.PIPE) { stdHandles[0] = -1L; } else if (redirects[0] == ProcessBuilderForWin32.Redirect.INHERIT) { stdHandles[0] = getHandle(FileDescriptor.in); } else { f0 = new FileInputStream(redirects[0].file()); stdHandles[0] = getHandle(f0.getFD()); } if (redirects[1] == ProcessBuilderForWin32.Redirect.PIPE) { stdHandles[1] = -1L; } else if (redirects[1] == ProcessBuilderForWin32.Redirect.INHERIT) { stdHandles[1] = getHandle(FileDescriptor.out); } else { f1 = newFileOutputStream(redirects[1].file(), redirects[1].append()); stdHandles[1] = getHandle(f1.getFD()); } if (redirects[2] == ProcessBuilderForWin32.Redirect.PIPE) { stdHandles[2] = -1L; } else if (redirects[2] == ProcessBuilderForWin32.Redirect.INHERIT) { stdHandles[2] = getHandle(FileDescriptor.err); } else { f2 = newFileOutputStream(redirects[2].file(), redirects[2].append()); stdHandles[2] = getHandle(f2.getFD()); } } return new ProcessImplForWin32(username, password, cmdarray, envblock, dir, stdHandles, redirectErrorStream); } finally { try { if (f0 != null) { f0.close(); } } finally { try { if (f1 != null) { f1.close(); } } finally { if (f2 != null) { f2.close(); } } } } } private  ProcessImplForWin32(

@Test public void testStart() { try { Process process = ProcessImplForWin32.start( "test123", StringUtils.EMPTY, new String[]{"net"}, null, null, null, false); Assert.assertNotNull(process); } catch (Error | Exception e) { logger.error(e.getMessage()); } try { Process process = ProcessImplForWin32.start( "test123", StringUtils.EMPTY, new String[]{"net"}, null, null, new ProcessBuilderForWin32.Redirect[]{ ProcessBuilderForWin32.Redirect.PIPE, ProcessBuilderForWin32.Redirect.PIPE, ProcessBuilderForWin32.Redirect.PIPE }, false); Assert.assertNotNull(process); } catch (Error | Exception e) { logger.error(e.getMessage()); } }
