I suggest to upgrade to the latest tomcat 7 release.

Martin, the problem is, its too huge a change, i know your suggestion is valid, 
but the change might have high impact on our systems. Still, will try to 
achieve that. 

Just a suggestion, please add this somewhere in your docs, so that people may 
know, before trying to upgrade.

Thanks,
Vishal Meghani

Hmm, do you have a suggestion where to add this hint?

Btw, you could also submit a pull request that adds some reflection to support 
also older versions of tomcat7.

Martin, i think setupAndConfiguration's Configure tomcat should be the right 
place to add this.

Its a nyc idea, to submit a pull request and use reflection, will do that if 
necessary. :)

Thanks for all your help.
