 From the jdb 'help', we have:
      [...]
   catch <class id> -- break when specified exception thrown
   ignore <class id> -- cancel 'catch' for the specified exception
      [...]
   <class id>: full class name with package qualifiers or a
   pattern with a leading or trailing wildcard ('*').

A user may believe they are requesting ALL exceptions under
(for example) java.lang via this command:
    > catch java.lang.*
    Set exception catch java.lang.*

They will be encouraged in that belief when they see confirmation
listed back:
    > catch
    Exceptions caught: exception catch java.lang.*

They will be surprised to learn that the PatternReferenceTypeSpec
will be resolved to the first class in the vm().allClasses()
list that isPrepared() and matches the <class id> pattern.

This means "catch java.lang.*" is not a request for all
exceptions under java.lang - it will be resolved into a
request for java.lang.ArithmeticException.

While that may be a reasonable interpretation, the user-surprising
piece is that the jdb 'catch' command continues to report:
    > catch
    Exceptions caught: exception catch java.lang.*
