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.
