---------------------------------
Attachment: (was: derby-6617-2.diff)
> Missing FilePermission makes boot fail with NPE
> -----------------------------------------------
>
> Key: DERBY-6655
> URL: https://issues.apache.org/jira/browse/DERBY-6655
> Project: Derby
> Issue Type: Bug
> Components: Services
> Reporter: Dag H. Wanvik
> Attachments: derby-6617-2.diff, derby-6617-2.status
>
>
> In experimenting with DERBY-6617, I looked at the "false" returned by
> FileMonitor#PBInitialize, ca line 157 when the code gets a SecurityException
> when trying to create the derby home directory. This will happen when running
> with a security manager and the necessary FilePermission has not been granted
> to derby.jar.
> Unfortunately, this leads to the boot failing with an NPE without explanation
> of the cause. [The repro patch does dump the reason to the console,]
> See the repro in the attached patch [^derby-6617-2.diff].
> This is the stack trace seen:
> {code}
> 1)
