Yeah we talked a while ago on #gentoo-java or was it on this mailing |
| 13 |
list that our approach to backwards compatibility is not enough to be |
| 14 |
able to always run things with 1.4 but using -source is enough to get us |
| 15 |
through the following situation: |
| 16 |
|
| 17 |
-appfoo depends on libfoo |
| 18 |
-libb depends on liba but only compiles against 1.4 class library |
| 19 |
-liba can be emerged with 1.6 |
| 20 |
|
| 21 |
So what I am trying to say here is that using -source 1.4 enables us to |
| 22 |
compile libb (if liba wasn't compiled to 1.4 bytecode, javac would fail |
| 23 |
with class version issues) but people should usually be running things |
| 24 |
with the latest stable JDK/JRE (this is what happens by default). |
