SunEC regression update

The latest security update of openjdk-7 caused a regression when applications relied on elliptic curve algorithms to establish SSL connections. Several duplicate classes were removed from rt.jar by the upstream developers of OpenJDK because they were also present in sunec.jar. However Debian never shipped the SunEC security provider in OpenJDK 7.

The issue was resolved by building sunec.jar and its corresponding native library libsunec.so from source. In order to build these libraries from source, an update of nss to version 2:3.26-1+debu7u8 is required.

Updates for the amd64 architecture are already available, new packages for i386 will be available within the next 24 hours.

For Debian 7 Wheezy, these problems have been fixed in version 7u231-2.6.19-1~deb7u2.

We recommend that you upgrade your openjdk-7 packages.
