RFR: 8028357: Unnecessary allocation in AliasFileParser

[Claes Redestad]

Hi,

some classes in jvmstat/perfdata code contains debug logging code 
predating the logging APIs, which
provokes some unnecessary allocation in certain applications.

Since the debug logging can't have been used for quite some time, I 
propose to remove it altogether
rather than converting it to the j.u.l. framework.
