If an 8-bit byte value is inserted into a Sybase TINYINT column, GenericJDBCException is thrown because of an arithmetic overflow during implicit conversion of a SMALLINT value to a TINYINT field.

This is happening for MixedTest.testMixedInheritance() and InterfaceProxyTest.testInterfaceProxies().

The full stacktrace is:

could not insert: [org.hibernate.test.interfaceproxy.SecureDocumentImpl]" type="org.hibernate.exception.
GenericJDBCException">org.hibernate.exception.GenericJDBCException: could not insert: [org.hibernate.test.interfaceproxy.Sec
ureDocumentImpl]
