No, contexts can't be shared across threads since information about the 
runtime execution is stored in the context.

There's a class org.mozilla.javascript.ContextFactory that can be
subclassed and installed via ContextFactory.initGlobal if you want to 
create and manage a pool of Contexts. You'll have to take care of
restoring the initial state of a Context when you reuse one.
