You should download ASF software from download pages on *.apache.org sites. :)
That jar is just some random piece of Tomcat 6.0.33. You cannot
download it and drop into any other Tomcat version.
It is useful if you need to compile your own code that uses those
internal APIs of Tomcat, but you should not use it at runtime at a
proper Tomcat instance.
If you look into META-INF/MANIFEST.MF file inside the jar you should see that
Specification-Title: Apache Tomcat
Specification-Version: 6.0
etc.

${owner['new']} is accessing property "new" of object "owner".
That is exactly the same that you tried with ${owner.new}.
The ${owner.isNew()} expression is a different beast - it is a method call,
and method calls support is introduced in JSP 2.2/Expression Language
2.2. You will have to use Tomcat 7.0.
