RFR : 6984762 : Invalid close of file descriptor '-1' in findZoneinfoFile

[Seán Coffey]

This issue was fixed in JDK 6 and JDK 8 some time back along with :
7092679: (tz) Java getting wrong timezone/DST info on Solaris 11

for some reason, the bad fd close fix never made JDK 7 and I'm looking 
to fix that now.
