[stdout] in Eclipse console prints two newlines

[kwutzke]

Hello,

I have got this issue:

http://www.eclipse.org/forums/index.php/m/754176/

Is this a JBoss AS 7.0.1 issue as mentioned in the above thread?

Thanks

What do your logging configurations and output look like? Also which file is it logged to?

P.S: 7.0.2 is the latest released version, you might want to try that instead of 7.0.1

My logging config in standalone.xml looks like this:

{code}
<subsystem xmlns="urn:jboss:domain:logging:1.1">
    <console-handler name="CONSOLE" autoflush="true">
        <level name="INFO"/>
        <formatter>
            <pattern-formatter pattern="%d{HH:mm:ss,SSS} %-5p [%c] (%t) %s%E%n"/>
        </formatter>
    </console-handler>
    <periodic-rotating-file-handler name="FILE" autoflush="true">
        <level name="INFO"/>
        <formatter>
            <pattern-formatter pattern="%d{HH:mm:ss,SSS} %-5p [%c] (%t) %s%E%n"/>
        </formatter>
        <file relative-to="jboss.server.log.dir" path="server.log"/>
        <suffix value=".yyyy-MM-dd"/>
        <append value="true"/>
    </periodic-rotating-file-handler>
    <logger category="org.jboss.as.jpa">
        <level name="WARN"/>
    </logger>
    <logger category="com.arjuna">
        <level name="WARN"/>
    </logger>
    <logger category="org.apache.tomcat.util.modeler">
        <level name="WARN"/>
    </logger>
    <logger category="sun.rmi">
        <level name="WARN"/>
    </logger>
    <root-logger>
        <level name="INFO"/>
        <handlers>
            <handler name="CONSOLE"/>
            <handler name="FILE"/>
        </handlers>
    </root-logger>
</subsystem>
{code}

Removing the trailing %n from the pattern-formatter pattern affects all output, logging and stdout. Removing the %n makes the other one-line logging output no a newline at all, two-newline outputs are one-line now. Worse than before.

What's wrong? Maybe a Windows only issue?? How do you fix this? This seems to affect all JBoss AS versions...

Can you post the actual logs please? Which version of Windows is this? Also which vendor and version of Java are you using?

[kwutzke]

I'm using JDK 7:

java version "1.7.0"

Java(TM) SE Runtime Environment (build 1.7.0-b147)

Java HotSpot(TM) 64-Bit Server VM (build 21.0-b17, mixed mode)

OS is Windows 7 Professional 64 bit, BUILD 7601 (SP1).

Snipped server.log is attached.

Maybe it is just telling you to stop logging via stdout and use a logger instead What happens if you switch to print instead of println? Does that happen on JDK 6 too? Does it happen on other OS as well?

public void println(String x)

Prints a String and then terminate the line. This method behaves as though it invokes PrintStream.print(String) and then PrintStream.println().
