> In an event evaluator which is called in the option part of an "ex" formatting specifier I cannot use a "throwable instanceof example" expression, because the evaluator receives a ThrowableProxy and not a Throwable.
> Here is a stack trace, dumped from the evaluator expression. It does include a ThrowableProxyConverter.convert call:
> java.lang.Exception: Stack trace
