Hello comunity,
I found a serious bug in JNET / servlet service framework in our cocoon
2.2 based application. After some time the following Exception pops up and
the only way to resolve is to restart the web application...
java.lang.NullPointerException

Any Ideas?
I found a Jira Thread of another project using cocoon and having similar
problems...
