Please note, the function I fail on was ResultSet's getDtring(String).

Will Base64 do?

Please note, the function I fail on was ResultSet's getDtring(String).

Seems like that the ODBC-driver for the database you're connecting
is behaving differently than expected by the bridge when returning
data leading to a core-dump of the virtual machine.

The JdbcOdbc-bridge shipped with Java is unsupported for nearly
8 years now, I also had problems e.g. connecting to the database
of Navision. What database are you trying to access? Look for a
JDBC-driver for that particular database instead of using ODBC.
Most databases have that nowerdays.

Ok, Ok...

I earned it the tough way.... ;-)

I meant "decode" of course...

I think you meant "understand" rather than "encode".

Float stack check sounds like Sun's code got confused about the depth
of the on-chip floating point stack. The on chip stack pointer is 3
bit and addresses a circular buffer of registers.

1. See if this happens in other JVMs or in Jet. See
http://mindprod.com/jgloss/jgloss/jet.html try both java -client and
java -server. Let the code run long enough for optimisers to kick in.
See http://mindprod.com/jgloss/benchmark.html

If you can show it happens in only one JVM, Sun will be much more
likely to take you seriously it is their problem.

2. reduce the code as much as you can and still trigger the FP stack
overflow/underflow.

If it happens only after a long time running, it is likely the
optimiser screwing up.
