-------------------------------------

             Summary: Edm.Decimal Literal Validation incorrect
                 Key: OLINGO-879
                 URL: https://issues.apache.org/jira/browse/OLINGO-879
             Project: Olingo
          Issue Type: Bug
          Components: odata2-core
    Affects Versions: V2 1.1.0
            Reporter: Michael Burwig
            Priority: Minor


The regex pattern (see below) that is used in {{EdmDecimal.java}} to validate Edm.Decimal literals is not in accordance with:
http://www.odata.org/documentation/odata-version-2-0/json-format/#PrimitiveTypes
http://www.odata.org/documentation/odata-version-2-0/overview/#AbstractTypeSystem

E.g. {{"0.0"}} is wrongfully recognized as a valid Edm.Decimal literal.

{code:title=EdmDecimal.java|borderStyle=solid}
  private static final Pattern PATTERN =
      Pattern.compile("(?:\\+|-)?(?:0*(\\p{Digit}+?))(?:\\.(\\p{Digit}+?)0*)?M|m)?");
{code}
