Bug #330735 told that freenet wasn't compatible with ant-core-1.8
Why was the restriction removed?

Anyways I face this problem right now, if I don't mask ant-core and ant-nodeps >=1.8

# emerge -avt freenet

These are the packages that would be merged, in reverse order:

This bug is also valid for net-p2p/freenet-0.7.5_p1277

It was not removed, as you can see in your own output:

>     =dev-java/ant-core-1.7 required by (net-p2p/freenet-0.7.5_p1275, ebuild

freenet still requires ant-core-1.7, but portage itself has problems with the dependency resolving, it pulls in the latest version for unspecified dependencies, which then collides with the requrested version for freenet.
Comment 3 Thomas Sachau gentoo-dev 2010-09-19 21:25:10 UTC
Suggested temporal workaround is either to mask the higher version (ant-core-1.8) or to try some newer portage version.

There's a fix in git to make portage handle this better:

Comment 5 Zac Medico gentoo-dev 2010-09-22 03:44:30 UTC
This is fixed in 2.1.9.10 and 2.2_rc86.

A regression related to the above commit is fixed here:
