Seems that it might be possible with this to start using some 1.5 language constructs in Derby's code: those that compile down to standard byte code. This would be by using -source 1.5 -target 1.4 in the build.xml files.
Be *very* careful about what 1.5 language features you start using in your code. It's not as easy as specifying -source 1.5 -target 1.4 to get a 1.4 compatible class/jar.
If you end up using the "wrong" language constructs in your code, you will become dependant on additional libraries like Retrowaver (or similar) that implements the missing features/classes for you.
In a former life we ended up writing 1.4 code and compiled using a 1.5 compiler to avoid additional dependencies.
"-target jsr14" seem to be supported now (it wasn't back then), and might solve this issue.
