Package : libbluray
Version : 1:1.1.0-1+deb10u1
Debian Bug : 1011716

The last Java security update introduced a change that broke libbluray's
interactive BD-J support. This update adds compatibility with those Java
changes.

For Debian 10 buster, this problem has been fixed in version
1:1.1.0-1+deb10u1.

We recommend that you upgrade your libbluray packages.
