Suppress logging of ClientAbortException in WroFilter. #534

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
When requesting wro/*.js or wro/*.css using browser, the following exception 
occurs on my web app with wro4j-core-1.4.8.1.jar.
But wro4j seems to work fine.
It works with apache-tomcat-7.0.29 and jdk1.7.0_05.

With wro4j-core-1.4.7.jar or before, I didn't see the exception.

Original issue reported on code.google.com by h.shiros...@gmail.com on 30 Aug 2012 at 12:45

The real problem is this:
"Caused by: ClientAbortException:  java.net.SocketException: Software caused 
connection abort: socket write error"

This error message generally means that the end that reported the error tried 
to write data, but the other end has already closed the connection.

It can easily be reproduced by hitting F5 in browser in "hammer" mode. This 
problem is harmless for both: client and server and there little that can be 
done, unless you want to make those logs less verbose.. 

Closing the issue with WONTFIX resolution. Feel free to reopen it if you don't 
agree.

Thank you for reply.

So I want to suppress logs since it's too verbose.
Is the following setting reasonable solution?

log4j.logger.ro.isdc.wro.http.WroFilter=FATAL

I would recommend using:

log4j.logger.ro.isdc.wro.http.WroFilter=NONE

Btw, I can suppress that log in next release.
Will change the title and description of this issue.

Thank you for fix.

BTW `log4j.logger.ro.isdc.wro.http.WroFilter=NONE`
didn't work for me. Log output was not suppressed. DEBUG level log was also 
shown.

I'll use `log4j.logger.ro.isdc.wro.http.WroFilter=FATAL` for now.
