      Description

      FULL PRODUCT VERSION :
      java version "1.8.0_151"
      Java(TM) SE Runtime Environment (build 1.8.0_151-b12)
      Java HotSpot(TM) 64-Bit Server VM (build 25.151-b12, mixed mode)

      ADDITIONAL OS VERSION INFORMATION :
      Microsoft Windows [Version 10.0.15063]

      A DESCRIPTION OF THE PROBLEM :
      The conversion from XmlGregoriaCalendar to GregoriaCalendar can result in incorrect timezone set if the original object has a timezone with the minutes set greter than 0 and less than 10.

      The result is:
      Original String in XML Resulting Gregorian Calendar
      2017-01-09T18:00:00.000+01:01 09-GEN-17 18:00:00,000000000 +11:00
      2017-01-09T18:00:00.000+01:02 09-GEN-17 18:00:00,000000000 +12:00
      2017-01-09T18:00:00.000+01:03 09-GEN-17 18:00:00,000000000 +13:00
      2017-01-09T18:00:00.000+01:04 09-GEN-17 18:00:00,000000000 +14:00


      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      GregorianCalendar c = new GregorianCalendar(2017, 0, 9, 18, 0, 0);
      c.setTimeZone( TimeZone.getTimeZone( "GMT+01:01" ) );
      XMLGregorianCalendar c2 = DatatypeFactory.newInstance().newXMLGregorianCalendar(c);
      c2.setTimezone( (1*60)+1 ); // sets the timezone in minutes

      System.out.println( "c2.toGregorianCalendar().getTimeZone() = " + c2.toGregorianCalendar().getTimeZone() );


      EXPECTED VERSUS ACTUAL BEHAVIOR :
      EXPECTED -
      The correct timezone is GMT+1:01, not GMT+11:00
      ACTUAL -
      c2.toGregorianCalendar().getTimeZone() = sun.util.calendar.ZoneInfo[id="GMT+11:00",offset=39600000,dstSavings=0,useDaylight=false,transitions=0,lastRule=null]

      ERROR MESSAGES/STACK TRACES THAT OCCUR :
      No error message or log

      REPRODUCIBILITY :
      This bug can be reproduced always.

      ---------- BEGIN SOURCE ----------
      GregorianCalendar c = new GregorianCalendar(2017, 0, 9, 18, 0, 0);
      c.setTimeZone( TimeZone.getTimeZone( "GMT+01:01" ) );
      XMLGregorianCalendar c2 = DatatypeFactory.newInstance().newXMLGregorianCalendar(c);
      c2.setTimezone( (1*60)+1 ); // sets the timezone in minutes

      System.out.println( "c2.toGregorianCalendar().getTimeZone() = " + c2.toGregorianCalendar().getTimeZone() );

      ---------- END SOURCE ----------

      CUSTOMER SUBMITTED WORKAROUND :
      A possible workaround is to avoid the method setTimezone of the XMLGregorianCalendar and use the setTimeZone of the GregoriaCalendar after conversion.

      I tracked down the error in method com.sun.org.apache.xerces.internal.jaxp.datatype.XMLGregorianCalendarImpl#getTimeZone

      An extract:
                  StringBuffer customTimezoneId = new StringBuffer(8);
                  customTimezoneId.append("GMT");
                  customTimezoneId.append(sign);
                  customTimezoneId.append(hour);
                  if (minutes != 0) {
                      customTimezoneId.append(minutes);
                  }

      If minutes is not zero is appended without the ':' separator.
