It's probably these last rule what is causing the issue

Rule Palestine	2020	max	-	Mar	Sat>=24	0:00	1:00	S
Rule Palestine	2020	max	-	Oct	Sat>=24	1:00	0	-

The failure seen is 

******************************
Asia/Gaza : Asia/Gaza
    -------------
    SimpleTimeZone (NG)
       stz=java.util.SimpleTimeZone[id=Asia/Gaza,offset=7200000,dstSavings=3600000,useDaylight=true,startYear=0,startMode=2,startMonth=2,startDay=-1,startDayOfWeek=7,startTime=0,startTimeMode=0,endMode=2,endMonth=9,endDay=-1,endDayOfWeek=7,endTime=3600000,endTimeMode=0]
      stz0=java.util.SimpleTimeZone[id=Asia/Gaza,offset=7200000,dstSavings=3600000,useDaylight=true,startYear=0,startMode=3,startMonth=2,startDay=24,startDayOfWeek=7,startTime=0,startTimeMode=0,endMode=3,endMonth=9,endDay=24,endDayOfWeek=7,endTime=3600000,endTimeMode=0]
