Examples with Handler java.util.logging.Handler used on opensource projects

Example 66 with Handler

use of java.util.logging.Handler in project bazel by bazelbuild.

the class BlazeRuntime method getTestCrashLogger.

/**
   * Returns a logger that crashes as soon as it's written to, since tests should not cause events
   * that would be logged.
   */
@VisibleForTesting
public static Future<Logger> getTestCrashLogger() {
    Logger crashLogger = Logger.getAnonymousLogger();
    crashLogger.addHandler(new Handler() {

        @Override
        public void publish(LogRecord record) {
            System.err.println("Remote logging disabled for testing, forcing abrupt shutdown.");
            System.err.printf("%s#%s: %s\n", record.getSourceClassName(), record.getSourceMethodName(), record.getMessage());
            Throwable e = record.getThrown();
            if (e != null) {
                e.printStackTrace();
            }
            Runtime.getRuntime().halt(ExitCode.BLAZE_INTERNAL_ERROR.getNumericExitCode());
        }

        @Override
        public void flush() {
            throw new IllegalStateException();

Example 67 with Handler

use of java.util.logging.Handler in project jetty.project by eclipse.

the class JavaUtilLogTest method setJUL.

@BeforeClass
public static void setJUL() {
    LogManager lmgr = LogManager.getLogManager();
    java.util.logging.Logger root = lmgr.getLogger("");
    // Remember original handlers
    originalHandlers = root.getHandlers();
    // Remove original handlers
    for (Handler existing : originalHandlers) {
        root.removeHandler(existing);
    }
    // Set test/capturing handler
    jul = new CapturingJULHandler();
    root.addHandler(jul);
}
