Re: [Help-jel] Evaluator.compile() thread safe

[Konstantin L. Metlov]

These methods perform a static initialization during the Evaluator class
loading and the initialized variables are then used in read-only fashion.
Basically, they initialize the ClassFile object and keep a copy, which is
then cloned for each compiled expression to avoid initializing it again
and again.

So, the short answer -- it should not break thread safety IMHO.

I remember to have introduced synchronization into JEL class loader to fix
a race condition, exposed in a heavily threaded environment. This means
that the rest of the code was fine.

With the best regards,
                         Konstantin.
