specializing jvmArgs in a derived class

[Deneau, Tom]

I have a base class with
    @Benchmark 
    public void myBenchmark()

and several derived classes that specialize that benchmark.
In one of the derived classes, I would like to specify that when that derived class forks, certain jvmArgs get added to the jvm command line.  Is there a way to do this?

When I tried this in the derived class

    @Override
    @Benchmark
    @Fork(jvmArgs="...") 
    public void myBenchmark()

I got this error which I don't really understand:
    Internal error: multiple methods per @Group, but not all methods have @Group
    
If I remove the @Benchmark annotation from the derived myBenchmark, that error goes away but the jvmArgs seems to also get ignored.
