[8u] RFR for JDK-8166872: GPL header in /hotspot/src/share/vm/gc_implementation/g1/g1RemSetSummary.cpp

[Shafi Ahmad]

Hi All,

Please review the trivial change of adding a comma after year in Copyright section.

Summary: 
Does not get it's GPL header swapped to commercial in the licensee source
bundle because of missing a comma after the second year.
