> 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) testMissingFilePermission(org.apache.derbyTesting.unitTests.junit.MissingPermissionsTest)java.lang.NullPointerException
