      Description

      FULL PRODUCT VERSION :
      java version "1.8.0-ea"
      Java(TM) SE Runtime Environment (build 1.8.0-ea-b123)
      Java HotSpot(TM) 64-Bit Server VM (build 25.0-b65, mixed mode)


      ADDITIONAL OS VERSION INFORMATION :
      Darwin Brainys-Mac-mini.local 13.0.0 Darwin Kernel Version 13.0.0: Thu Sep 19 22:22:27 PDT 2013; root:xnu-2422.1.72~6/RELEASE_X86_64 x86_64

      A DESCRIPTION OF THE PROBLEM :
      For date-time string formats both ISO 8601 and RFC 3339 allow either a long time zone offset including a colon and minutes like this: +01:00
      _and_ they allow a shorter offset without the colon and minutes like this: +01

      The "ZonedDateTime" class included in Java 8's new java.time.* classes is documented as parsing ISO 8601-like strings. While true of the longer time zone offsets, the shorter offsets cause the class to throw a DateTimeParseException, like this:

      java.time.format.DateTimeParseException: Text '2013-12-11T21:25:04.800842+01' could not be parsed at index 26

      Here is some demonstration source code???

              String x = "2013-12-11T21:25:04.800842+01:00";
              String y = "2013-12-11T21:25:04.800842+01";
              
              ZonedDateTime zonedDateTime_x = ZonedDateTime.parse( x ); // Succeeds.
              ZonedDateTime zonedDateTime_y = ZonedDateTime.parse( y ); // Fails.



      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      Simply run these 4 lines of code.

              String x = "2013-12-11T21:25:04.800842+01:00";
              String y = "2013-12-11T21:25:04.800842+01";
              
              ZonedDateTime zonedDateTime_x = ZonedDateTime.parse( x ); // Succeeds.
              ZonedDateTime zonedDateTime_y = ZonedDateTime.parse( y ); // Fails.


      EXPECTED VERSUS ACTUAL BEHAVIOR :
      EXPECTED -
      Both calls to "parse" should succeed.
      ACTUAL -
      The second call to "parse" throws an exception like this one:

      java.time.format.DateTimeParseException: Text '2013-12-11T21:25:04.800842+01' could not be parsed at index 26

      ERROR MESSAGES/STACK TRACES THAT OCCUR :
      java.time.format.DateTimeParseException: Text '2013-12-11T21:25:04.800842+01' could not be parsed at index 26

      REPRODUCIBILITY :
      This bug can be reproduced always.

      ---------- BEGIN SOURCE ----------
      String x = "2013-12-11T21:25:04.800842+01:00";
      String y = "2013-12-11T21:25:04.800842+01";

      ZonedDateTime zonedDateTime_x = ZonedDateTime.parse( x ); // Succeeds.
      ZonedDateTime zonedDateTime_y = ZonedDateTime.parse( y ); // Fails.
