    Several bugs were fixed that could, under certain circumstances,
    disrupt the upgrade of the Java and ca-certificates packages.

    For Debian 11 bullseye, this problem has been fixed in version
    20230710~deb12u1~deb11u1.

    We recommend that you upgrade your ca-certificates-java packages.

    For the detailed security status of ca-certificates-java please refer to
    its security tracker page at:
    https://security-tracker.debian.org/tracker/ca-certificates-java
