[GROOVY-5077] GroovyCastException after upgrade from Groovy 1.7.10 to 1.8.3 - ASF JIRA

Details

Type: Bug
Status: Open
Priority: Major
Resolution: Unresolved
Affects Version/s: 1.8.3
Fix Version/s: 4.x
Component/s: parser
Labels:
None
Environment:
n.a.

Description

Have a catetegory with

  public static Object asType(Byte p_byteSelf, Class<?> p_class)
  {
    //...
    return new MyClass(p_byteSelf);
  }

With Groovy 1.7.10 the script

  def v
  v = (byte)15 as MyClass

worked fine.

With Groovy 1.8.3 a org.codehaus.groovy.runtime.typehandling.GroovyCastException is thrown.

Has the operator precedence been changed?

Could you try with :

def v
v = (Byte)15 as MyClass

Primitives are handled differently since 1.8.

A related problem occurred in a production environment with the code snippet

XTextCursor curText = (XTextCursor)xTextDocument.getText().createTextCursor()

which throws the exception

the new parser Parrot will parse "(byte)15 as MyClass" as follows:
((byte)15) as MyClass

Can you provide some runnable test case?
