Subject [jira] [Updated] (DBCP-322) CPDSConnectionFactory.validateObject(Object) ignores Throwable
Date Wed, 21 Dec 2011 19:11:32 GMT

     [ https://issues.apache.org/jira/browse/DBCP-322?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Phil Steitz updated DBCP-322:
-----------------------------

    Fix Version/s:     (was: 1.4.1)
                       (was: 1.3.1)
                   2.0

This is a behavior change that could conceivably break some applications, so pushing to 2.0

> CPDSConnectionFactory.validateObject(Object) catches and ignores Throwable, which is
a bit excessive. For example:
> {code}
> if (rset != null) {
>     try {
>         rset.close();
>     } catch (Throwable t) {
>         // ignore
>     }
> }
> {code}
> close() can only throw SQLException, and that is all that should be ignored. In particular,
ThreadDeath should never be ignored.
> Same applies to KeyedCPDSConnectionFactory.
> Basic[Managed]Datasource also catch Throwable, but rethrow it as SQLNestedException.
> This is a bit better, but there's still the problem with ThreadDeath.
