Quite an outdated info. InterClient 2.01 is at least 6 year old technology
without any updates since original release as opensource. Jaybird had
already 4 releases behind it, approaching the 5th. The JDBC connection pool
that comes with Jaybird has PreparedStatement cache, but I think Hibernate
uses its own, there should be no issue there at all (but if there is, report
it here and we will fix it).
