FIX "hasOwnProperty" for "execParams"
UB has old bug with execParams.
Specifically, execParams.hasOwnProperty('code')
won't work even though code is there!
But execParams.code
works just fine.
I always forget about this bug and every now and then spend some time realizing it is not a bug in my code, but in UB.
I also realized it is not tracked and not logged (or is it?). Please fix.
