RFR 8235930 : java.util.regex.PrintPattern does not print a link to the next node

[Ivan Gerasimov]

Hello!

The java.util.regex package contains a debugging utility PrintPattern 
which is used to display the internal representation structure of a 
compiled regex pattern.

When it prints a node that is linked to another node that has already 
been printed, it is supposed to print a link, but fails.

The error is due to ambigous overloading of print() method.

Would you please help review a trivial fix?

No regression test because the utility is not something officially 
supported.
