There hasn't been a public announcement about this one, presumably because it's a prerelease, but we do rely on it. As I understand it, both Oracle's Java 8 and IcedTea's Java 7 were affected so this package must be too. I will bump it imminently but only ppc64 has been marked stable for this SLOT so far.
ppc64 team, please stabilise: dev-java/icedtea-bin-3.0.0_pre10
Stable for PPC64.
Thanks! Old removed. Security team, please continue.
Added to existing GLSA request.
