Description Aaron Oneal 2013-04-19 15:59:22 UTC
The try/catch around the predicate in Mono's AggregateException.Handle needs to be removed so that predicates can throw an unwrapped exception.

According to MSDN:
http://msdn.microsoft.com/en-us/library/system.aggregateexception.handle.aspx

"If any invocations of the predicate throws an exception, it will halt the processing of any more exceptions and immediately propagate the thrown exception as-is."

Right now Mono is catching any exceptions thrown from the predicate and wrapping it in an AggregateException before rethrowing, which prevents a common pattern of using Handle to unwrap an AggregateException to throw a clean one.
