Knut Anders Hatlen commented on DERBY-4856:
-------------------------------------------

I think this is OK as long as the classes are only used by the sane jars. If you plan to use the classes in the production jars too, you should be aware of the discussion in DERBY-289, which raises some concerns about having code in the shared packages.

> On system crash or session ending error, Derby should dump as much information as possible. Such as: forcing a javacore if possible or at least thread dump and system environment information. This should only occur if a running session crashes not on boot error due to fail recovery etc.
> The IBM jvm provides a way to programmatically dump a javacore. i.e. com.ibm.jvm.Dump.JavaDump() And, the SUN jvm will force a thread dump using the Unsafe class and there may be a better way.
