[Owasp-csrfguard] NullpointerException in org.owasp.csrfguard.CsrfGuardFilter.doFilter

[Stephan, Frank]

Hi,

I am using owasp-csrfguard 3.0.0.503. I configured web.xml and cpoied
the jar into the classpath.
The filter gets executed - as expected - but I get the following
exception 

java.lang.NullPointerException
	
org.owasp.csrfguard.CsrfGuardFilter.doFilter(CsrfGuardFilter.java:53)

It looks like the HttpRequest is not passed into the method.

When implementing my own filters, everything works fine.

The full stack trace is.
