LuciferYang opened a new pull request, #7732:
URL: https://github.com/apache/kyuubi/pull/7732
### Why are the changes needed?
Closes #7731.
`ReflectUtils.getField` and `invokeAs` wrapped the whole body in one `try`
and rewrote any `Exception` as `RuntimeException(s"$clz does not have ...",
e)`. Because `bind`/`get`/`invoke` ran inside that same `try`, a failure thrown
by the found field or the invoked method itself was relabeled as a missing
member, and the real exception survived only as the cause.
This moves the `try`/`catch` to wrap only the lookup
(`DynFields`/`DynMethods` `build`/`buildChecked`). The "does not have" message
now applies only when the lookup fails; a failure while binding, reading, or
invoking the found member keeps its own type and message.
### How was this patch tested?
Added two `ReflectUtilsSuite` cases: an invoked method that throws
`IllegalArgumentException("bad input")` must propagate that exception rather
than a "does not have" message, and binding a `Class` target to an instance
field must surface the field wrapper's "Cannot bind"
`IllegalArgumentException`. Both fail if the catch is widened back over the
invocation.
