Hi every body,  
I’m a new HTM tester, my background is strong Java developpement, so my question, is it (HTM.java) similar, in term of perfs/most freshness features to the Python one? should I go dig deeper in it?  
I was able to run java HotGym, it works well.

Hi @zahir_hamroune,

HTM.java is slightly behind in development but has a one-to-one correspondence features-wise.

Cheers,
