Oh good! I was hoping to hear that.

But here, on my machine with default config, i'm compiling
commons-daemon, and it says "using sun-jdk-1.6".
Watch this:

# emerge -1 commons-daemon

Oh, and even if i set the system VM to 1.5, it still uses sun-jdk-1.6.
Strange! Look:

# java-config -L
The following VMs are available for generation-2:
*)      Sun JDK 1.5.0.13 [sun-jdk-1.5]
2)      Sun JDK 1.6.0.03 [sun-jdk-1.6]


Why that? I don't find any particular line in commons-daemon's ebuild
which specifies, that it should use JDK 1.6 instead of JDK 1.5.
The dependencies are >=virtual/jdk-1.4 and such.


Is this a bug, maybe?
