java - What are %I% and %G% identifiers in Object class javadoc? -

-

just out of curiosity.

when hover on object word in eclipse, doc shows below info. know version represent.

this not appear on online oracle javadocs http://docs.oracle.com/javase/7/docs/api/java/lang/object.html

enter image description here

also, futher checking object class, intial comments show %w% %e%. know these identifiers for?

those come sccs (source code control system), scm sun used use. when file checked in %i% converted version of file , %g% date file checked in. if memory serves correctly sun moved mercurial around 2007 or so, don't think there's danger of these getting updated!

%e% date (in yy/mm/dd format, %g% mm/dd/yy). don't know %w%!
