If I give incorrect value for

I get NPE when connecting to a database through ij

> Provide a rolling file implementation of derby.log
> --------------------------------------------------
>
> Key: DERBY-6350
> URL: https://issues.apache.org/jira/browse/DERBY-6350
> Project: Derby
> Issue Type: Improvement
> Components: Miscellaneous
> Reporter: Brett Bergquist
> Priority: Minor
> Labels: features
> Attachments: rollingfilelog.patch.txt, rollingfilelog.patch.txt,
> rolling_file_patch_5.txt, rolling_file_patch_6.txt
>
>
> By default, derby.log grows without bounds if the derby.infolog.append
> property is set to "true". Setting this to "true" helps in a hands off
> production environment to ensure that if Derby restarts, the derby.log which
> might contain important information is not lost. On the other hand, when set
> the "true" the derby.log grows without bounds. This is problematic in a long
> running system.
> What is really needed is the ability to have a rolling derby.log file support
> where the maximum file size and maximum number of files can be specified.
> Derby has the ability to configure the location of the log file (ie.
> derby.stream.error.file) and also two methods of redirecting the error stream
> (.ie derby.stream.error.method and derby.stream.error.field). There is no
> standard implementation that supports a rolling derby.log however.
> This facility should be part of the core Derby system so that it works in
> both embedded and network server models.
