             Summary: ClassFormatError using method reference on interface target
                 Key: GROOVY-9853
                 URL: https://issues.apache.org/jira/browse/GROOVY-9853
             Project: Groovy
          Issue Type: Bug
    Affects Versions: 3.0.7
            Reporter: Christopher Smith


After upgrading to 3.0.7, using {{interfaceField::method}} is resulting in bytecode output containing an InterfaceMethodref that looks as expected. When running it in the Eclipse JUnit runner, however (which I think is unimportant), I'm getting a loading error from the JVM:

{code}
Caused by: java.lang.ClassFormatError: Invalid constant pool index 130 in class file com/example/sendgrid/SendgridMailSender (not a method)
{code}

where the offending constant is

{code}
  #130 = InterfaceMethodref #126.#129     // com/sendgrid/SendGridAPI.api:(Lcom/sendgrid/Request;)Lcom/sendgrid/Response;
{code}

from the 4.6.8 SendGrid SDK.

Compiling with 3.0.6 seems to work. Replacing {{::}} with {{.&}} seems to work.

The JVM is 11.0.9-hs-adpt.
