Description

Example of Calendar instance parsed from document:

java.util.SimpleTimeZone[id=unknown,offset=7200000,dstSavings=3600000,useDaylight=false,startYear=0,startMode=0,startMonth=0,startDay=0,startDayOfWeek=0,startTime=0,startTimeMode=0,endMode=0,endMonth=0,endDay=0,endDayOfWeek=0,endTime=0,endTimeMode=0]

Although calling e.g. timeZone.getDisplayName() shows correclty 'GMT+02:00', timeZone.toZoneId() fails with following stack trace:

java.time.zone.ZoneRulesException: Unknown time-zone ID: unknown
	at java.time.zone.ZoneRulesProvider.getProvider(ZoneRulesProvider.java:272)
	at java.time.zone.ZoneRulesProvider.getRules(ZoneRulesProvider.java:227)
	at java.time.ZoneRegion.ofId(ZoneRegion.java:120)
	at java.time.ZoneId.of(ZoneId.java:411)
	at java.time.ZoneId.of(ZoneId.java:359)
	at java.time.ZoneId.of(ZoneId.java:315)
	at java.util.TimeZone.toZoneId(TimeZone.java:556)
        ...

This is fixed in PDFBOX-1633 but although the fixVersion is 1.8.3, I couldn't find the commit on 1.8 branch (only on 2.0)
