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

             Summary: 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


Groovy does not allow the definition of literal byte constant. 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}
