If you do not want to replace the line you can override the setting made by the original class in a subclass like this.
Code:
public class HSQLDialect_HHH_1598 extends org.hibernate.dialect.HSQLDialect {
public HSQLDialect_HHH_1598() {
super();
registerColumnType(Types.BIT, "boolean");
// Assert that the new type is registered correctly.
if (!"boolean".equals(getTypeName(Types.BIT))) {
throw new IllegalStateException("Failed to register HSQLDialect "
+ "column type for Types.BIT to \"boolean\".");
}
}
}
Just replace the value for hibernate.dialect with the name of this class.
