v4.pl and Java warning (I-TASSSERv2.0)

Hi,
During the threading process, the following warning was recorded in wdPPA, MUSTER and wPPAmod files (a line per C-terminal 76 residues). Question: Can this be ignored or does it require action of some kind?

'Use of uninitialized value $ROUND in regexp compilation at v4.pl line 295, line 77'
