Data converters logs contain some meaningless information

[rgorodischer]

Here's a piece of log:
INFO: ..converting vrp_5_4_1
Mar 5, 2014 1:02:51 PM sun.reflect.GeneratedMethodAccessor18 invoke
INFO: ..converting vrp_72_4_1
Mar 5, 2014 1:02:51 PM sun.reflect.GeneratedMethodAccessor18 invoke
INFO: ..converting vrp_76_10_1
Mar 5, 2014 1:02:51 PM sun.reflect.GeneratedMethodAccessor18 invoke
INFO: ..converting vrp_76_10_2
Mar 5, 2014 1:02:51 PM sun.reflect.GeneratedMethodAccessor18 invoke
INFO: ..converting vrp_76_14_1
Mar 5, 2014 1:02:51 PM sun.reflect.GeneratedMethodAccessor18 invoke
INFO: ..converting vrp_76_14_2

Only lines which start with INFO should be in the correct log.
