openjdk-8, openjdk-lts regression
=========================================================================
A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 18.04 LTS
- Ubuntu 16.04 LTS

Summary:

USN-3804-1 introduced a regression in OpenJDK.

Software Description:
- openjdk-lts: Open Source Java implementation
- openjdk-8: Open Source Java implementation

Details:

USN-3804-1 fixed vulnerabilities in OpenJDK. Unfortunately, that update
introduced a regression when validating JAR files that prevented Java
applications from finding classes in some situations. This update
fixes the problem.

We apologize for the inconvenience.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 18.04 LTS:
