Ron Gavlin commented on TUSCANY-1843:
-------------------------------------

Luciano,

You might also want to apply the following patch so that the tests compile on 
JDK 1.4 as well. Is it possible for you to update the build for at least the 
das-rdb module to use the JDK 1.4 compiler? This would hopefully catch problems 
like this one.

Thanks,

- Ron
