Re: [aspectj-users] Aspectjweaver.jar outputting on stderr vs stdout

[Eric B <ebenzacar@xxxxxxxxx>]

Hi Andy,

Was anything ever done about this, or a ticket opened for it?  I'm running AJ 1.8.10 and still seeing the same behaviour, so I figure it was probably never addressed (ticket or otherwise).

Thanks,

Eric

Ok - thanks for the confirmation.  I will have to let the team know that all ERROR logs are not actual ERROR logs, but only INFO logs.

First time I've ever looked at that bit of code but I do see the code says this in the WeavingAdaptor:

protected void createMessageHandler() {

messageHolder = new WeavingAdaptorMessageHolder(new PrintWriter(System.err));

So all messages sent to that message handler will go to System.err, regardless of severity. That seems a bit crappy. I guess presumably it was done to avoid messages messing up whatever your app was doing on System.out (possibly even just to make testing easier - look for app output on System.out and look for weaver output on System.err).

It should be configurable but right now I can't see any way you can influence it.

cheers,

Andy

I'm using AspectJ 1.6 with JBoss 4.2.1 configured with LoadTimeWeaving.

I have added the aspectjweaver.jar to the startup parameters:

 -javaagent:c:/dev/Java/aspectj1.6/lib/aspectjweaver.jar 

AspectJ is properly loaded and indeed is weaving my classes as desired/expected.  However, any weaveinfo data that it is producing is being logged as an "Error" as it appears in the stderr stream instead of the stdout:

2016-10-06 13:31:40,310 ERROR [STDERR] [UnifiedClassLoader3@333cf5e3] weaveinfo Join point 'method-call(business.impl.BusinessContext business.ejb3.ManagerBean.getBusinessContext(izone.business.BusinessContextInfo))' in Type 'business.ejb3.ManagerBean' (ManagerBean.java:112) advised by afterThrowing advice from 'common.security.logger.AccessDeniedLoggerAspect' (AccessDeniedLoggerAspect.java)

According to the JBoss documentation, System.err stream is redirected into a category called STDERR, which is what I see above.

Is there a way to configure the weaver to output on stdout instead?  Or is it working this way by design?

Thanks,

Eric
