问题
On two supposedly identical machines, I am having two different startup results for Tomcat 6.0.24. I am using Java version 1.7_09 on both, yet get wildly different results.
The problem is that I apparently can not use Java encoding names in Tomcat6, as stated below:

However, on another machine I get a successful start:

I do not know what is different between the two that would allow one machine to permit Java encoding, while another can not.

Very similar problem with a solution (related to a missing jar) outlined in the oracle forums that might be useful.:
