In the past the Low Level REST Client was super careful not to wrap any exceptions that it throws from synchronous calls so that callers can catch the exceptions and work with them. The trouble with that is that the exceptions are originally thrown on the async thread pool and then transfered back into calling thread. That means that the stack trace of the exception doesn't have the calling method which is *super* *ultra* confusing. This change always wraps exceptions transferred from the async thread pool so that the stack trace of the thrown exception contains the caller's stack. It tries to preserve the type of the throw exception but this is quite a fiddly thing to get right. We have to catch every type of exception that we want to preserve, wrap with the same type and rethrow. I've preserved the types of all exceptions that we had tests mentioning but no other exceptions. The other exceptions are either wrapped in `IOException` or `RuntimeException`. Closes #28399 |
