Subject [jira] [Commented] (DERBY-5936) AllocPage.ReadContainerInfo throws ArrayIndexOutOfBoundsException at arraycopy

Rick Hillegas commented on DERBY-5936:
--------------------------------------

Hi Petr,

This sounds like a problem in the ARM layer. Here are some questions I would pursue if I were
debugging this:

1) Is it always the same .dat file, with the same conglomerate number? Alternatively, does
the .dat file always correspond with the same table name?

2) Do any other .dat files contain that text?

3) Since Derby is only being used as a cache, could it run as an in-memory database instead?

Hope this helps,
-Rick
