Hi,

I'm using this driver with home-grown connection pool (I do not use
FBWrappingDataSource though) on Windows, Sun JDK 1.3.1 b24 (or
something like that, one that is shipped with JBuilder 7), Firebird
server runs on Linux. I never experienced such problems. PoolMan works
ok if some methods in FBResultSetMetaData are fixed (in current
version they are not implemented). I had some problems when using
built-in JDBC pool in one Resin installation (I do not know its
version), it almost crashed my server because pool was not reusing
connections but always opened a new one. Anyway, I haven't seen JVM
core dump.

I would say that this is bug in JVM. I'm not sure if it is possible to
crash VM core by executing some Java code, if VM is bug free. :) We do
not use any native code in the driver, only plain Java + socket
communication...

Best regards,
Roman Rokytskyy
