Benjamin McCann commented on WW-2240:
-------------------------------------
That line in the source is a logging call. Simply add the following around the
call:
if(LOG.isInfoEnabled()) {
}
That will solve the problem 90% of the time. It's not the correct solution,
which should still be investigated, but should be added regardless for
performance reasons. Info logs should always be checked in this manner and
debug logs checked with isDebugEnabled().

> Using struts2-core-2.1.0-SNAPSHOT-20071003.jar, I received the following:
> java.lang.NullPointerException
> at
> org.apache.struts2.interceptor.FileUploadInterceptor.intercept(FileUploadInterceptor.java:277)

> com.opensymphony.xwork2.DefaultActionInvocation$1.doProfiling(DefaultActionInvocation.java:229)

> at
> com.opensymphony.xwork2.DefaultActionInvocation.invoke(DefaultActionInvocation.java:226)
> My action was able to access the File, so it must have been something in the
> cleanup. My action was very similar to the one found in this tutorial
