How e.printStackTrace result get printed inside logs - wildfly

I am using wildfly and I am having no idea how all e.printStackTrace statement get printed in server.log file of wildfly.
What is the configuration behind that. Please explain.

System.out and System.err are redefined to go to jboss logging.
Take a look at the JDK Javadoc

Eclipse doesnt show -Djavax.net.debug=ssl,handshake debug logs

I have configured eclipse runconfigurations as follows;
at Run configurations-->Arguments
-Djavax.net.debug=ssl,handshake
eclipse runtime.
But still at console im not getting any debug logs.(SSL handshake logs)
Why is that?
I get only my system.print statements in console.
Make sure, to configure it as VM argument, not as Program argument.

Where is Spring Tool Suite's error log? ("See Error Log for more details")

Spring Tool Suite gives me a cryptic error that also says:
See Error Log for more details
QUESTION: Where can I find the error log of Spring Tool Suite?
Nothing in Eclipse's "Console" view
I launched STS from command line, but nothing special is shown on command line, some debug information but nothing that looks like an error

Why does eclipse close by itself while running?

It's been happening lately for some unknown reason.I have the latest version of Eclipse ADT (25 Sept 2014) and it just shuts off while I'm working. Any ideas?
Start Eclipse from a terminal to see the standard output. Chances are that the Java VM runs into a problem because of SWT which can crash the VM. Note: If you're using Windows, you may have to use java.exe instead of javaw.exe to get output.
Also look into the Error Log. Eclipse has a view for that or look into the file .../workspace/.metadata/.log The file might contain an error message.
If you find an error in either the console or the error log, let us know and we might be able to help.
The issue could also be because of the JVM that was chosen for the project.

Is it possible to disable traces printed to console in JBoss 5.1?

By default there are two appenders in JBoss5.1 - CONSOLE and FILE.
Do we need to use both of these appenders in production?
Is it possible to use FILE appender only?
I removed CONSOLE appender from web\conf\jboss-log4j.xml but there are still a lot of traces in console.
Why?
I do not want traces in console in production.
Is it possible to turn CONSOLE appender off?
Maybe it's the output of the run.sh or run.bat, that doesn't use log4j.
Are you on windows or linux?
Do you see the output when you're booting or when you're deploying (or using) your application?
The CONSOLE appender is useful for development, particularly on Windows, where the appserver is run as a foreground console process. Also, Windows makes it rather hard to tail a log file like you can on *nix.
So no, you don't have to use the console appender. You can put whatever you like in the log4j file, the default is just the default. Remove appenders, or add them, however you see fit.

JBoss: What does the warning EJBTHREE-1246 from the InterceptorRegistry mean?

I am currently developing an EJB 3.0 based application on the JBoss AS 5.0.0.GA and just recently the following warning showed up in the server log:
09:50:19,735 WARN [InterceptorsFactory] EJBTHREE-1246: Do not use InterceptorsFactory with a ManagedObjectAdvisor, InterceptorRegistry should be used via the bean container
09:50:19,735 WARN [InterceptorsFactory] EJBTHREE-1246: Do not use InterceptorsFactory with a ManagedObjectAdvisor, InterceptorRegistry should be used via the bean container
09:50:19,735 WARN [InterceptorRegistry] applicable interceptors is non-existent for ...
...
The warnings are generated as soon as an EJB (a stateless session bean) is injected into a backing bean of my JSF web-application. The beans do work without problems though, but I still would like to know where that warning comes from and what I can do to avoid it.
I have already searched a bit around, but haven't found a good answer (some say, bean developers do not have to worry, but its a warning, so I'd like to have a better solution):

JBoss JIRA Issue about the warning (Not that helpful in my opinion)
So has anyone an explanation what causes the warning (in terms of a bean developer, not application server developer) and what to do to avoid it?
Update: I've just upgraded JBoss to 5.0.1.GA (Download, Release-Notes) but unfortunatly the warning still appears.
As far as I understand all the available sources on this warning, it is nothing a user of JBoss 5 can do anything about and is essentially just a reminder for the developers of JBoss that they use their own classes wrong.
Following the advice from the developers, I am now ignoring it by changing my logging configuration in conf/jboss-log4j.xml. I've just added:
<category name="org.jboss.ejb3.interceptors">
<priority value="ERROR" />
</category>
Even the JBoss EJB3 tutorial/documentation says you can safely ignore these warnings. Well if everyone can ignore these don't log them! It's frustrating to see this issue isn't being fixed.
I had the same problem, modify the ejb3-interceptors-aop.xml, and now works ok.
I've tried this modification in ejb3-interceptors-aop.xml
I've comment these lines :
<aspect name="InterceptorsFactory" factory="org.jboss.ejb3.interceptors.aop.InterceptorsFactory" scope="PER_INSTANCE"/>
<advice name="invoke" aspect="InterceptorsFactory"/>
and it Works
The warnings no longer appear in JBoss 5.1.0, but adding the category as Simon posted eliminates the logging of the warnings in 5.0.x
Just follow the steps
Stop JBoss and right click on the server instance and select clean
right click on the project and select run -> run configurations
select classpath -> add jars
Add Jars from JBoss ASHOME/client - jbossall-client.jar,JBoss ASHome/common/lib - all jars.
Apply and run.
