Jalview can fail to properly import and map a structure to a sequence via its N&W aligner

Jalview can fail to properly import and map a structure to a sequence that was entered manually via 'specify PDB ID'.. and doesn't warn the user that something went wrong, just shows the structure without creating a mapping.

Originally noted as: Cannot map 7zbc to its Uniprot sequence OPSD_MACFA - ArrayIndexOutOfBoundsException
Attempting to (manually load) PDB 7zbc for Uniprot sequence OPSD_MACFA results in the structure being shown but with no mapping to the alignment created, just an exception on the console:
java.lang.ArrayIndexOutOfBoundsException: Index 39 out of bounds for length 39
