[infinispan-issues] [JBoss JIRA] (ISPN-1430) advancedCache.addInterceptorXYZ method don't inform the caller if the operation fails

[Manik Surtani (Commented) (JIRA)]

    [ https://issues.jboss.org/browse/ISPN-1430?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12643303#comment-12643303 ] 

Manik Surtani commented on ISPN-1430:
-------------------------------------

Ah, my bad.  CacheImpl in turn calls InterceptorChain.addXYZ() and the latter *does* return a boolean:

Just that this isn't passed out to API. :)

> Problem:
> cache.getAdvancedCache().addInterceptorAfter(new ErrorInducingInterceptor(), NonTransactionalLockingInterceptor.class);
> if NonTransactionalLockingInterceptor doesn't exist in the chain then the method return silently without informing the user that it didn't succeed. This is not API friendly.
> Suggested solution: throw an exception to inform the user that his attempt is not correct.
