While testing some new jar files in CTW, I tripped across a new failure in the type system having to do with the instance_id field of TypeInstPtr.

#=== Meet Not Symmetric ===
#t   =                   java/lang/Object:NotNull:exact *
#this=                   javax/resource/spi/ConnectionRequestInfo:NotNull *
#mt=(t meet this)=       java/lang/Object:NotNull *
#t_dual=                 java/lang/Object:AnyNull:exact *,iid=top

and this version which is pretty much the same except for the names.

#=== Meet Not Symmetric ===
#t   =                   java/lang/Object:NotNull:exact *
#this=                   org/netbeans/core/output2/NbIO:NotNull *

For the moment you can grab the jars jboss-jca.jar and org-netbeans-core-output2.jar from my home but I'll be putting these into the our full CTW set.
