The problem there is knowing when that is the case. For test/hotspot/jtreg/runtime/classFileParserBug/TestEmptyBootstrapMethodsAttr.java the message "Main method not found in class" comes from the launcher and is a localized error string, but there is no way for the test author to know that without digging into the source to check. We have hundreds of tests that check exception messages and they are not affected by this problem as exception messages are not, it seems, localized. So there is a bit of an inconsistency in that regard.

How? There's no way to name the desired message so that you could ask for it. And you'd still need to know it was a message that was localized.

The current fix seems okay as a patch of the current set of issues, but really there should be some way to avoid being hit by this with future tests IMO.
