you are using some piece of software (com.mypkg.packaging.*) that is

tomcat code.
It expects to find a method in org.apache.tomcat.util.IntrospectionUtils
that is no longer there in 6.0.26, which causes the NoSuchMethodError.
Basically your embedder does not support this version of Tomcat, you
should
contact the vendor, they should do the recompile .
It's interesting that the Java Runtime throws a NoSuchMethodError since
the return type is not technically part of the method signature. I've
never considered this before, and it totally makes sense because the
return type really is an important part of the method. Just interesting
to note that the effective method signature is not the same as the
official one.
Another thing to note is that the Tomcat folks have made an unstable
change, here, by changing a public API. It would have been better to
create a method with a new signature and deprecated the old one, while
leaving it there.
The Tomcat developers have always considered this to be part of the internal
API, not the public API. This is true of most of the classes under the
org.apache.tomcat package.
