I guess the goal is to put
void close() throws;
into java.io.Closeable, and still retain source-level compatibility.

When a block calls a throws method, checks for checked exceptions are
disabled for this block. This is required because otherwise, existing
client code would not compile anymore.
A block which does not call such a method needs to use a catch-throws
clause. Previously, it could not catch those exceptions, so there
isn't a compatibility issue.
