> Key: GEODE-8830
> URL: https://issues.apache.org/jira/browse/GEODE-8830
> Project: Geode
> Issue Type: Bug
> Components: native client
> Affects Versions: 1.12.0, 1.13.0, 1.13.1
> Reporter: Mario Salazar de Torres
> Assignee: Mario Salazar de Torres
> Priority: Major
> Labels: pull-request-available

> Under several transactional scenarios exceptions are converted from its more
> specific type to *Exception* type within the internal code of the native
> client. The scenarios are the following ones:
> # Whenever a transaction commit conflicts the native client user would
> expect a *CommitConflictException*, but instead the user can only catch an
> exception of type *Exception*.
> # Whenever a transaction prepare conflicts the native client user would
> expect a *CommitConflictException*, but instead the user can only catch an
> exception of type *Exception*.
> # Whenever rollback/prepare/commit is executed with no transaction ongoing
> the native client user would expect an *IllegalStateException*, but instead
> the user can only catch an exception of type *Exception*.
> ----
> *Example:*
> {code:c++}
> auto tx_manager = cache.getCacheTransactionManager();
> // First transaction starts here
> tx_manager->begin();
> region->put("key", "A");
> // First transaction is suspended before doing the commit
> auto& tx_id = txm->suspend();
> // Second transaction starts here
> tx_manager->begin();
> region->put("key", "B");
> tx_manager->commit();
> // After successfully committing the second transaction, the first
> transaction is resumed
> tx_manager->resume(tx_id);
> try {
> tx_manager->commit();
> }
> catch(CommitConflictException& ex) {
> // This is what should be in the output in this example
> std::cerr << "A conflict occurred while committing the transaction!" <<
> std::endl;
> }
> catch(Exception& ex) {
> // However, as there is some issue with exception handling, this is what's
> currently shown
> std::cerr << "An unknown exception occurred while committing the
> transaction!" << std::endl;
> }{code}
