We are aware of the problem and will release an update shortly. I have
already replied to the debian-lts list here [1]

Summary:

Upstream removed duplicate classes from rt.jar because they are also
present in sunec.jar. Debian has never shipped sunec.jar in OpenJDK 7,
(see also [2]] so the removal causes applications that rely on Elyptic
Curve algorithms to fail. The current workaround is to use a different
security provider or to downgrade openjdk-7 to the previous version
which can be downloaded from snapshots.debian.org.
