Hi All, I've got some code using Velocity which failed under load. Can you confirm that the Velocity class is meant to be thread-safe? If so, I'll file a bugreport.
Scenario: * Velocity version 1.6.1, java 1.6, linux (also fails with velocity-1.6.4) * Using a complex template with macros * Using a separate context object per thread * Invoking Velocity.evaluate(context, out, "", templateText) Results: * Under heavy load from single thread, all ok * Under light load from multiple threads, all ok * Under heavy load from multiple threads, macro references like "#macroname" intermittently don't get invoked during template processing; the "#macroname" text appears literally in the output instead. Simply replacing calls to Velocity.evaluate(...) with VelocityEngine ve = new VelocityEngine(); ve.init(props); ve.evaluate(...) fixes the issue. I've confirmed the problem with a unit test; I can simplify it and submit it if this really is considered a bug. >From the documentation, email lists, etc. I believe that using the Velocity singleton *should* have worked here (we don't need multiple velocity configurations). Comments?
