Fails at runtime with @CompileStatic and two nested with

    XMLWordPrintableJSON

Details

    Description

      Consider this class:

      package testgroovy

import groovy.transform.CompileStatic

@CompileStatic
class Foobar {
    
    static class Foo {
        String aaa = 'aaa'
        String bbb = 'bbb'
    }
    
    static class Bar {
        String ccc = 'ccc'
    }
    
    Foo foo = new Foo()
    Bar bar = new Bar()
    
    void foobar() {
        foo.with {
            bar.with {
                println aaa
                println bbb
                println ccc
            }
        }
    }

    static void main(String[] args) {
        new Foobar().foobar()
    }    
}

      It fails at runtime with:

      Exception in thread "main" java.lang.ClassCastException: testgroovy.Foobar$Bar cannot be cast to groovy.lang.Closure
    at testgroovy.Foobar$_foobar_closure1$_closure2.doCall(Foobar.groovy:23)
    at testgroovy.Foobar$_foobar_closure1$_closure2.call(Foobar.groovy)
    at org.codehaus.groovy.runtime.DefaultGroovyMethods.with(DefaultGroovyMethods.java:369)
    at org.codehaus.groovy.runtime.DefaultGroovyMethods.with(DefaultGroovyMethods.java:316)
    at testgroovy.Foobar$_foobar_closure1.doCall(Foobar.groovy:22)
    at testgroovy.Foobar$_foobar_closure1.call(Foobar.groovy)
    at org.codehaus.groovy.runtime.DefaultGroovyMethods.with(DefaultGroovyMethods.java:369)
    at org.codehaus.groovy.runtime.DefaultGroovyMethods.with(DefaultGroovyMethods.java:316)
    at testgroovy.Foobar.foobar(Foobar.groovy:21)
    at testgroovy.Foobar.main(Foobar.groovy:31)

      It works fine if you remove @CompileStatic.
