> This was reported by one of our users who was testing cache transactions and other operation with changing topology. He claims that he had to catch {{ClusterTopologyException}} directly in some cases, so he had to write the code like this:
> {code}
> try (final Transaction tx = txn.txStart()) {
>     ...
> }
> catch (final CacheException e) {
>     if (!(e.getCause() instanceof ClusterTopologyException)) {
>         throw e;
>     }
>     // retry
>     failure = e;
> }
> catch (final ClusterTopologyException e) {
>     // retry
>     failure = e;
> }
> {code}
> Cache operations should throw only {{CacheException}}. Need to revisit exception handling logic.
