Description:   Opened: 2006-11-25 09:51 0000 
In the ebuild:
# javadoc does not build correctly with 1.6
DEPEND="
        doc? ( =virtual/jdk-1.4* =virtual/jdk-1.5* )
        !doc? ( >=virtual/jdk-1.4 )

Trying to emerge:

 * Using: sun-jdk-1.6
>>> Unpacking source...

The good thing is that this is a corner case but at the very least we should
document that this is not supported at this time or implement the needed code
to fix this.

My doc? atom was missing || ( ) but adding that did not help.

depend-java-query is the script that does the real magic. the java-utils-2 does
calls in to figure out what -target / -source / vm to use. depend-java-query
gets passed the DEPEND/RDEPEND (depending on the situation).

depend-java-query is very naive, in that it only checks for known patterns, ie
=virtual/jdk-1.4*, >=virtual/jdk-1.5. In particular, it doesn't deal use flags.
so in the example, it sees >=virtual/jdk-1.4 as being the 'best' match, so uses
that.

JAVA_PKG_NV_DEPEND can be used to explicitly say what to pass to
depend-java-query. This is used in a few cases (ie dev-util/eclipse-sdk), but
doesn't seem to be documented at all.

http://overlays.gentoo.org/proj/java/changeset/3334
http://dev.gentoo.org/~betelgeuse/patches/java-utils-2.eclass-use.patch

With these two changes you can use conditional DEPEND/RDEPEND values.

Fixed in 2.0.31.
