Error Question

Hello all,

 

I am in the process of developing a Servlet application.  I am currently
using Eclipse Helios and Tomcat 6.0.29 in my dev environment.  When I
start up Tomcat in Eclipse I get the following error pasted below.  What
does this mean and how do I resolve it?  Thank you.

Not sure how you can be two places at once...

"Might", rather than "should".  It would at least eliminate one possibility.

I am currently at JVM 1.6.0_11 and am using JDK 1.6.20.  So updating the
JVM should resolve the issue?  I will give it a try.  Many thanks.

Regards,

What JVM are you using?  There was a known bug in 6u* that threw an
erroneous string index out of bounds exception on occasion.  The problem
was fixed in 6u22 (or possibly earlier).
