I get the following verify error:

java.lang.VerifyError: Bad type on operand stack

when I convert anonymous class to lambda inside super constructor call in inner class. (myRubyScriptFactory  - is a final field of the outer class.)

 

Before (works normally):

public RubyRunConfigurationFactory() {
  super(RubyRunConfigurationType.this, new Function<Project, AbstractRubyRunConfiguration>() {
    public AbstractRubyRunConfiguration fun(Project project) {
      return new RubyRunConfiguration(project, myRubyScriptFactory);
    }
  });
}

 

After (verify error):

public RubyRunConfigurationFactory() {
  super(RubyRunConfigurationType.this, project -> new RubyRunConfiguration(project, myRubyScriptFactory));
}
