In org.firebirdsql.ngds.isc_db_handle_impl debugger is stoped on the
line with asterisks
(87) public int getRdb_id() {
(88) checkValidity();
(89)*** return rdb_id;
(90) }

rdb_id value is 0
No exceptions thrown (well there is one since first jaybird is trying to
load .dll and than .so file but this is irrelevant)
Now when I continue, application is supposed to go back to
org.firebirdsql.ngds.GDS_Impl method isc_attach_database

public void isc_attach_database(String file_name, isc_db_handle
db_handle, DatabaseParameterBuffer databaseParameterBuffer) throws
GDSException
{
if (db_handle == null)
{
throw new GDSException(ISCConstants.isc_bad_db_handle);
}

DatabaseParameterBuffer cleanDPB =
removeInternalDPB(databaseParameterBuffer);

final byte[] dpbBytes = databaseParameterBuffer == null ? null :
((DatabaseParameterBufferImp)cleanDPB).getBytesForNativeCode();

synchronized(this)
{
native_isc_attach_database( getServerUrl(file_name),
db_handle, dpbBytes ); <- called from this line
} <-must return here


parseAttachDatabaseInfo(isc_database_info(db_handle,describe_database_info,1024),db_handle);
}


But it stops....
I read FAQ supplied with jaybird, but I found information how to disable
logging, not how to enable it.
Can this information help to track down the problem?
