javazic produces an incorrect table for time zones to be excluded in the per-GMT offset lists. As a result, TimeZone.getAvailableIDs(int) produces an incorrect time zone list.

This problem was fixed in 7090844. The same fix needs to go to the Tzupdater tool build system.

EVALUATION Port the JDK 8 fix to tzupdater javazic.
