Hey all,
I have several issues with Java while trying to install dev-java/lucene-2.4.1
I know what causes the error, but I don't know how to fix it. The output is here:

The first half of the build succeeds, but the second one fails. I bolded some things for you. First, it's trying to use 1.4 source when it needs 1.5. There is nothing in the ebuild to set that option, so it must be set on the system somewhere.
Second, notice how it says that my vm is icedtea-6? After it failed the first time I switched my vm to sun-jdk whatever the latest is, and did the usual env-update && source /etc/profile thing, but it still uses icedtea. Java-config reports that sun-jdk is in fact selected.
I recompiled javacc and ant but as you can see, I still get this error. How do I fix this?
Thanks.
EDIT: Forgot to mention, that I do have python 2.6.x installed:
[ebuild R ] dev-lang/python-2.6.4-r1
So no Python 3 related messes.

Thanks geki. That worked perfectly. Now the ebuild in portage needs to be changed.

No not perfectly, it has covered the symptom without fixing the cause (being javacc). it could even lead to worse issues.

so, how to fix the cause? 
where does the generics code come from?
I see javacc depends on 1.4. hmm ...

javacc has a JDK_VERSION (or similar) property that influences code compatibility ( aka its like the -source option to javac, but is really the target of javacc).
javacc-5.0 is the first version (I believe) to have set this to default to 5/1.5.
So the real solution is to patch the build.xml file to pass this property.

I'll leave that to the Java herd to fix then. I'm just beginning in Java, so I don't know how to fix it by patching the build.xml file.
Thanks for your quick replies everyone.
