[perl #118505] [JVM] Null PMC access when declaring constant for export twice

[Christian Bartolomaeus via RT]

There is no NullPointerException in the REPL anymore:

$ perl6-j
To exit type 'exit' or '^D'
> constant %a is export = 5 => 5; constant %a is export = 5 => 5
===SORRY!=== Error while compiling <unknown file>
Redeclaration of symbol %a
at <unknown file>:2
------> <BOL>⏏<EOL>

I'm closing this ticket as 'resolved'.
