[DBCP] org.apache.commons.dbcp2.datasources.InstanceKeyDataSourceFactory.closeAll()
does not close all
org.apache.commons.dbcp2.datasources.InstanceKeyDataSourceFactory.closeAll()
does not close all if one of delegated close() calls throws an exception.
I would think we would want to close all no matter what and then save the
first exception caught and rethrow it after all closes have been attempted.
Thoughts?
Gary

Throw the first one and add others as being suppressed?
+1 to respect the naming and log any error (or store errors and let the
caller do it if logging is an issue, something like db.closeAll(); if
(db.hasError()) db.getErrors().forEach(log::error))

Good question.
I’ve never liked `close()` methods that throw exceptions. What is the client code supposed to do?
It certainly makes sense to me to first fulfill the promise of “closeAll”, which is to call `close` on all values (and not stop half-way through).
The remaining question is what to do with any exceptions (there could be multiple) that occurred during this process.
One idea is to rethrow the first one. Another is to throw a MultipleExceptions from which the client code can obtain all exceptions that occurred. But then again, given that there is little that the client code can do with these exceptions, why not _return_ a list of the exceptions that occurred?
