Interface calculation fails for some entries

E.g. 2v52 and 2y27. The stack trace:

This is an issue in biojava parsing. Probably easiest way to solve it is upgrading to biojava 5 when it's out.

These 2 work ok now, I guess because of recent remediation at PDB? I'll close, please reopen if issue found for other examples.
