> Use Throwable.initCause() to improve error reporting
> ----------------------------------------------------
>
> Key: DERBY-2472
> URL: https://issues.apache.org/jira/browse/DERBY-2472
> Project: Derby
> Issue Type: Improvement
> Components: JDBC, Miscellaneous
> Affects Versions: 10.3.0.0
> Reporter: Kristian Waagan
> Priority: Minor
> Attachments: derby-2472_initial_patch.diff, setStackTrace-v2.diff,
> setStackTrace.diff
>
>
> As Derby has moved to J2SE 1.4, Throwable.initCause() can now be used to
> improve error reporting.
> As stated in the initial commit (that was backed out, see below):
> 'Set Throwable.initCause() in a couple of locations at the JDBC level where
> we setup nested SQLExceptions.
> This means that automatically the stack trace for a database failed to start
> includes the reason
> for the failure, rather than just "see next exception". This is a great help
> when running
> JUnit tests and getting failures to start a database.'
> The initial commit was backed out because it broke numerous tests under JDK
> 1.6, and the author indicated he had no time to investigate.
> The patch caused no failures when running the tests with Java SE 5.0.
