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

             Summary: Compiler compiles class with private abstract method
                 Key: GROOVY-7793
                 URL: https://issues.apache.org/jira/browse/GROOVY-7793
             Project: Groovy
          Issue Type: Bug
          Components: bytecode, Compiler
    Affects Versions: 2.3.11
         Environment: - OS X
- Java(TM) SE Runtime Environment (build 1.8.0_66-b17)
- IntelliJ Idea 14 CE \w Groovy plugin
- Gradle 2.2
            Reporter: Simo Tuokko


Using Groovy and JDBI in following class:

abstract class ItemDAO {
    @SqlUpdate("...")
    @GetGeneratedKeys
    private abstract long insertItem(@BindBean Item item)
}

When class is used JDBI will create proxy-implementation based on the the abstract class (or interface).

It will compile without any issues, but running it causes (shown below) class-loading/verify error. This is programmers fault to have "private abstract" methods, but I guess Groovy-compiler should not let this thru? Maybe IntelliJ Idea groovy-plugin should say it's illegal as well?

I haven't tried this with the latest Groovy-version but unless it has been specifically fixed it might still occur?
