If you disable the primitive optimization or enable invoke-dynamic the generated bytecode does not contain a "fast-path" branch and this tends to resolve debugging issues.  You can try this out in your case by setting a CompilerConfiguration on GroovyClassLoader.

{code:java}
if (groovyLoader == null) {
  CompilerConfiguration groovyConfig = new CompilerConfiguration();
  groovyConfig.setOptimizationOptions(Collections.singletonMap("int", false)); // or "indy", true
  groovyLoader = new GroovyClassLoader(GroovyClass.class.getClassLoader(), groovyConfig, true);
}
{code}

>          Issue Type: Bug
>          Components: bytecode

> Greetings,
>  
> I am using Groovy 2.4.15 under NetBeans 8.2 and Java 8 on a 64 bit Linux box.
>  
> I am dynamically loading Groovy with the following code:
>  
> if (groovyLoader == null)
> groovyLoader = new GroovyClassLoader(GroovyClass.class.getClassLoader());
> groovyClass = groovyLoader.parseClass(new GroovyCodeSource(new File(path + sourceFile)), false);
>  
>  
> Doing it this way, when debugging the loaded class, I am able to set breakpoints from within IntelliJ and it works as expected.  However, NetBeans & VSCode ignore the breakpoints.
>  
> I do a similar thing with Java files, and NetBeans & VSCode honors those breakpoints.
>  
> There must be something different between dynamically loaded Java and dynamically loaded Groovy.
>  
> Thanks.
