Is Template (render) thread safe?

[zacMode]

Hi, i'm new to this library (and ANTLR), but looking to add it to a project. I'm trying to understand how a Template instance should be used. Is it safe to parse a liquid string once and then use the single Template instance concurrently to render different strings?

e.g.

Template template = Template.parse(" hello, {{ name }}");

final ExecutorService executorService = Executors.newCachedThreadPool()
for (int i  = 0; i < 10_000; i ++) {
  executorService.submit(()-> template.render(Map.of("name", randomName())));
}

Thanks!

We made a lot of effort in moving forward to that, but still, no.
Each render call redefine internal templateContext field, so it is not safe yet to use this in multi-threaded env.

Keeping this ticket open until it will be thread-safe.

Also errors() method depends on the context, so we cannot do it local/parameter. it should be field.

Using Thread local for that is problematic. (we want know errors as long as it could)
