For org/apache/catalina/core/ApplicationFilterChain.doFilter package is org/apache/catalina/core/, class/file name is ApplicationFilterChain and method name is doFilter

Packages usually start with reversed domain name (org/apache) but technically it can be 1 depth package like
foo/Bar.baz or even 0 - no package Bar.baz

Maybe something like this ^(?<packageName>.+\/)?(?<filneame>.+\.)(?<functionName>.+)$ ?

@petethepig is this correct (and does the client send this already or do we need to make a change somewhere)
