http://issues.apache.org/bugzilla/show_bug.cgi?id=44032 ------- Additional Comments From [EMAIL PROTECTED] 2008-01-15 07:03 ------- We had a similar problem. The problem is that we use an AsynchAppender and a SocketAppender for logging. Because of how AsynchAppender works, it is possible that ThrowableInformation.getThrowableStrRep() runs on one LoggingEvent at the same time. public String[] getThrowableStrRep() { if(rep != null) { return (String[]) rep.clone(); } else { StringWriter sw = new StringWriter(); PrintWriter pw = new PrintWriter(sw); throwable.printStackTrace(pw); pw.flush(); LineNumberReader reader = new LineNumberReader( new StringReader(sw.toString())); ArrayList lines = new ArrayList(); try { String line = reader.readLine(); while(line != null) { lines.add(line); line = reader.readLine(); } } catch(IOException ex) { lines.add(ex.toString()); } rep = new String[lines.size()]; lines.toArray(rep); } return rep; } The problem is with ThrowableInformation.rep. If the first concurrent thread gets only to rep = new String[lines.size()]; and then the next concurrent thread gets to if(rep != null), then only rep.clone(); is returned with an empty array. Then later concurrent thread #1 will fill up the array but that's already late for the another concurrent thread. I think in this case the solution would be either to a) synchronize on ThrowableInformation.getThrowableStrRep() or b) modify rep = new String[lines.size()]; lines.toArray(rep); in method with String[] tempRep = new String[lines.size()]; lines.toArray(tempRep); rep = tempRep; -- Configure bugmail: http://issues.apache.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
