[infinispan-issues] [JBoss JIRA] (ISPN-4535) size() operator on JPACacheStore should expect larger than int

[Sanne Grinovero (JIRA)]

Sanne Grinovero commented on ISPN-4535:
---------------------------------------

I'm not sure what should be done, but casting to int is definitely wrong as you will have larger results.
Would at least be better to log an error rather than throwing a cast exception.

+1 for your idea of a "saturated cast", but it needs to be documented.

Ideally, the API needs to be changed in .next

> the return type of the CacheStore#size() is int but it's common in databases to store way more.
> The query performing the count operation is doing a cast to integer, this will fail.
