The MKS shell 647N/A * implementations were notoriously buggy. Implementing these tests purely 0N/A * in Java is not only portable but also robust. 0N/A // The version string to force a re-exec 0N/A // The Cookie or the pattern we match in the debug output. 0N/A * SIGH, On Windows all strings are quoted, we need to unwrap it 0N/A // Trim the string and remove the enclosed quotes if any. 0N/A * This method detects the cookie in the output stream of the process. 0N/A // Return the value asap if not in debug mode. 0N/A * This method return true if the expected and detected arguments are the same. 0N/A * Quoting could cause dissimilar testArguments and expected arguments. 0N/A * A convenience method for identical test pattern and expected arguments 647N/A * These tests require that a JVM (any JVM) be installed in the system registry. 647N/A * If none is installed, skip this test. 647N/A "no java found in system registry.");
