Fix for java.lang.VerifyError in tomcat 7.0.19 all the way thru tomcat 7.0.27!!

[Anjan Bacchu]

Hi all,

  I've been a tomcat user for about 10 years -- starting with 3.x. So
thanks the user and dev community for all the help.

I recently tried moving our appserver from 5.5 to 7. as soon as I deployed
our webapp to tomcat 7.0.27 and tried the app, I got a
java.lang.VerifyError.
down below is the stack Trace. this happens after I have entered the
credentials to the login page and POSTing it to another jsp (ChLogin.jsp).

I noticed that this error doesn't happen in tomcat 7.0.16 but happens in
tomcat 7.0.19 and all the way to 7.0.27.

Should I stay back with tomcat 7.0.16 OR can tomcat dev fix the bug so we
get the latest /nicest version ?

P.S : I downloaded the tar.gz version of tomcat and deployed it on RHEL 5.3
on tomcat 1.6.0_26 all thru 1.6.0_31.

Thank you very much,

BR,
