[FIXED] Re: NullPointerException when redeploy webapp, possible WSS4J leak

[Jose María Zaragoza <de...@gmail.com>]

Hello:

For you information , I could solve this issue . I was talking about this
in Tomcat mail list and we found 2 solutions:

a) upgrading to Tomcat 7.0.41
b) setting

-Dorg.apache.catalina.loader.WebappClassLoader.ENABLE_CLEAR_REFERENCES=false


in Tomcat 6.x


But I couldn't find the root cause for memory leak
I don't understand why the log reference in DOMReference.java is setted to
null by Tomcat
I use sl4j + logback + jcl-over-slf4j . I tried to upgrade to the lastest
release of this libraries , but it fails again




Regards
