Description

 

I'm compiling this little Closure with @CompileStatic enabled

scriptEngine.config.tap {
  // Code generation goes wrong here    
  optimizationOptions["indy"] = true
  // This code is generated correctly
  optimizationOptions.indy = true
}

// Generated fault code - obviously no call to getOptimizationOptions()
boolean var2 = true;DefaultGroovyMethods.putAt(((Class)((_main_closure1)this).getDelegate()).cast<invokedynamic>(((_main_closure1)this).getDelegate()), "indy", var2);
// Correct code for the second line, via setProperty
boolean bool1 = true;ScriptBytecodeAdapter.setProperty(Boolean.valueOf(bool1), null, ((CompilerConfiguration)((_main_closure1)this).getDelegate()).getOptimizationOptions(), (String)"indy");

Compilation works, but I get a runtime error, which is easily explicable given the generated code:
Exception in thread "main" org.codehaus.groovy.runtime.typehandling.GroovyCastException: Cannot cast object 'org.codehaus.groovy.control.CompilerConfiguration@15d9bc04' with class 'org.codehaus.groovy.control.CompilerConfiguration' to class 'java.util.Map'
