RuntimeException that is thrown and caught in response to a lua error.
{@link LuaError} is used wherever a lua call to {@code error()} would be used within a script.
Since it is an unchecked exception inheriting from {@link RuntimeException}, Java method signatures do notdeclare this exception, althoug it can be thrown on almost any luaj Java operation. This is analagous to the fact that any lua script can throw a lua error at any time.
