>             Project: Hibernate Core
>          Issue Type: Bug
>          Components: core
>    Affects Versions: 3.6.5, 4.0.0.Beta2
>         Environment: linux, jdk 1.6, hibernate latest from master, oracle 11gr2

> When using a _ at SecondaryTable(name="xx")_, set to optional using _ at org.hibernate.annotations.Table(name="xx",optional=true)_ the documentation states that the secondary table row will only be populated if any one of the properties mapped to the secondary table are not-null.  However, this does not work with joined subclasses using the _JoinedSubclassEntityPersister_.  This is because, internally, the boolean which controls "outer joinability" (called _isNullableTable_) always returns _false_.
> A fix has been tested which will be put into a github pull request. 
> The fix implements _isNullableTable_ to honor the optional flag.
> Unfortunately, there is no way I could find to really test whether the code is working, as it requires examining the SQL generated for various operations.  However, I have manually verified the fix.  Please look at the output of the _JoinedSubclassAndSecondaryTable_ test, which has been modified as well, to verify the DML statements.
> Fix available for 3.6.5 upon request. github pull will be for 4.0 (master).
