Fix UnnecessaryThrows to check actual close() method exceptions#812
Conversation
The recipe was incorrectly removing throws declarations from methods using try-with-resources because it made blanket assumptions that all Closeable types throw IOException and all AutoCloseable types throw Exception. Instead, the fix looks up the actual close() method on the resource type and checks what exceptions it declares, using the same mechanism already used for method invocations. Fixes #728
