Inconsistent treatment of Errors by CallbackPreferringPlatformTransactionManager [SPR-15749]

[spring-projects-issues]

Philippe Marschall opened SPR-15749 and commented

Most places in spring-tx treat RuntimeException and Error equally rolling back in both cases as both of them are unchecked. This can be seen in TransactionAspectSupport. completeTransactionAfterThrowing and DefaultTransactionAttribute. rollbackOn

The execution path for CallbackPreferringPlatformTransactionManager seems to be different
https://github.com/spring-projects/spring-framework/blob/master/spring-tx/src/main/java/org/springframework/transaction/interceptor/TransactionAspectSupport.java#L319
where an Error is not thrown but instead wrapped in a ThrowableHolderException. However looking at the code in UOWActionAdapter.run (used by the only present implementation of CallbackPreferringPlatformTransactionManager) any kind of Throwable seems to cause a rollback. It seems to me as if RuntimeException and Error should be treated equally in the CallbackPreferringPlatformTransactionManager path in TransactionAspectSupport.java
