hello all, the default java.util.logging.SimpleFormatter, used by default with the java.util.logging.ConsoleHandler, outputs one or two lines for logging messages plus the optional stack-trace if an exception is logged. the proposed formatter, always uses one line plus the optional stack-trace.
any objections on adding this class to the gnu.classpath.debug package? to try it, add the following to your logging.properties file --assuming you will be using the console handler: java.util.logging.ConsoleHandler.formatter = gnu.classpath.debug.Simple1LineFormatter cheers; rsn

+/**
+ * A simple 1-line formatter to use instead of the 2-line SimpleFormatter used
+ * by default in the JDK logging handlers.
+ * <p>
+ * The fixed format of this formatter is as follows:
+ * <p>
+ * <ol>
+ * <li>Date: As a yyyy-MM-dd string.</li>
+ * <li>Time: As a HH:mm:ss.SSSS Z string.</li>
+ * <li>Thread identifier, right-justified, and framed in an 11-digit field.</li>
+ * <li>Class name, without its package name, left-justified, and framed in a
+ * 30-character field.</li>
+ * <li>Method name, left-justified, and framed in a 30-character field.</li>
+ * <li>Level name, left-justified, and framed in a 5-character field.</li>
+ * <li>User message and arguments.</li>
+ * <li>Platform-dependent line-separator.</li>
+ * <li>Optionally, if the log-record contains a thrown exception, that
+ * exception's stack trace is appended to the output.</li>
+ * </ol>
+ * <p>
+ * Here is an example of the output generated by this formatter:
+ * <p>
+ * <pre>
