Tapestry 5.2.4 issue

Hi, 

upgraded to 5.2.4 today and I get the following error:

tried to access field org.slf4j.impl.StaticLoggerBinder.SINGLETON from class
org.slf4j.LoggerFactory

haven't seen anything on the forum about it, any ideas?

Thanks

Zubair

Hi Zubair

Is this your error: http://www.slf4j.org/faq.html#IllegalAccessError ?

> This error is caused by the static initilizer of the LoggerFactory class attempting to directly access the SINGLETON field of org.slf4j.impl.StaticLoggerBinder. While this was allowed in SLF4J 1.5.5 and earlier, in 1.5.6 and later the SINGLETON field has been marked as private access.

Take a look at this:

Cheers.
Alejandro.

If upgrading didn't help, you have multiple slf4j libs in the
classpath (newer api than impl). Using maven? Run mvn dependency:tree.

Thanks, did that and same issue - upgraded to 1.6.1

How would I find out which libraries are using slf4j internally?

But the only thing I changed was tapestry 5.2.1 to 5.2.4.  All other
libraries stayed the same.  

I'll keep digging

This is not related to Tapestry at all. You probably have mismatched SLF4J  
packages.

Abraço!
