["Dag H. Wanvik (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/DERBY-6619?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Dag H. Wanvik updated DERBY-6619:
---------------------------------

    Attachment: derby.log
                derby-6619.status
                derby-6619.diff

Uploading a patch [derby-6619.diff] which prints warnings on derby.log.

For example, with this invocation:
{code}
{code}
which uses the default security manager, the derby.log looks as in [^derby.log].

> As part of the fix for DERBY-3745, Derby silently swallows security exceptions and leaks class loaders. This can give rise to denial-of-service attacks. At a minimum, Derby should report the swallowed exceptions so that the security policy can be corrected and the application can be hardened against this attack. The swallowing occurs at these locations:
> {noformat}
> org.apache.derby.impl.services.timer.SingletonTimerFactory run Catch java.lang.SecurityException 0 line 175
> org.apache.derby.impl.services.timer.SingletonTimerFactory run Catch java.lang.SecurityException 1 line 158
> {noformat}
