FULL PRODUCT VERSION :


A DESCRIPTION OF THE PROBLEM :
"public static ZonedDateTime parse(CharSequence text)" method from java.time.ZonedDateTime does fails to parse all ISO 8601 format.

For example, ZonedDateTime.parse("2017-01-01T00:00:00.000+0000"); fails but ZonedDateTime.parse("2017-01-01T00:00:00.000+00:00"); works when both format should be accepted according to ISO-8601 requirements.

C.f. https://en.wikipedia.org/wiki/ISO_8601 : "An offset of zero, in addition to having the special representation "Z", can also be stated numerically as "+00:00", "+0000", or "+00""

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
 ZonedDateTime.parse("2017-01-01T00:00:00.000+0000");

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Method should return a valid instance of class ZonedDateTime.
ACTUAL -
Method throws java.time.format.DateTimeParseException

ERROR MESSAGES/STACK TRACES THAT OCCUR :
java.time.format.DateTimeParseException: Text '2017-01-01T00:00:00.000+0000' could not be parsed at index 23

REPRODUCIBILITY :
This bug can be reproduced always.

---------- BEGIN SOURCE ----------
    public void test() {
        ZonedDateTime zonedDateTime = ZonedDateTime.parse("2017-01-01T00:00:00.000+0000");
    }
---------- END SOURCE ----------

CUSTOMER SUBMITTED WORKAROUND :
Use another time format
