> Unable represent literal byte costant
> -------------------------------------
>
> Key: GROOVY-9366
> URL: https://issues.apache.org/jira/browse/GROOVY-9366
> Project: Groovy
> Issue Type: Bug
> Affects Versions: 2.5.9
> Reporter: paolo di tommaso
> Priority: Major
>
> Groovy does not allow the definition of literal byte constants. This makes impossible to express byte constant in some use cases.
> First example:
> {code:java}
> public @interface Version {
> byte value();
> }
> class Foo {
> @Version(0x01) String bar
> }
> Error: Attribute 'value' should have type 'java.lang.Byte'; but found type 'int' in @Version
> {code}
>
> Second example:
> {code:java}
> public @interface Version {
> byte value();
> }
> class Foo {
> @Version(1 as byte) String bar
> }
> Expected '(byte) 1' to be an inline constant of type byte in @Version
> at line: 6, column: 14Attribute 'value' should have type 'java.lang.Byte'; but found type 'java.lang.Object' in @Version
> at line: -1, column: -1 {code}
>
> Third example:
> {code:java}
> public @interface Version {
> byte value();
> }
> class Foo {
> public static final byte ONE = 0b01
> @Version(ONE) String bar
> }
> Expected 'ONE' to be an inline constant of type byte not a field expression in @Version
> at line: 7, column: 12Attribute 'value' should have type 'java.lang.Byte'; but found type 'java.lang.Object' in @Version
> at line: -1, column: -1
> {code}
>
