[jira] [Updated] (GROOVY-9206) Cannot use annotation with attribute of type char

["Eric Milles (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/GROOVY-9206?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Eric Milles updated GROOVY-9206:
--------------------------------
    Description: 
Consider the following:
{code:groovy}
import java.lang.annotation.*;
@Target(ElementType.FIELD)
public @interface A {
  char value();
}

​class C {
  @A((char)';')
  String tokens
}
{code}

This errors with: {{Expected '(char) ;' to be an inline constant of type char in @A}}.  I've tried a bare 1-character string literal, coercion, an int literal, and assignment to a static final field/property with similar results.  Not sure if it is possible to use this annotation without some kind of fix.
