Can I still use Java 7
Because Java 7 community support ends on 29 July 2022, applications hosted on App Service will continue to run, but they will not receive updates or security patches. To minimize risk and potential security vulnerabilities, upgrade your Web Apps to Java 11 or 8 depending on your workload requirements.
Is Java 7 backwards compatible
The backwards compatibility means that you can run Java 7 program on Java 8 runtime, not the other way around. There are several reasons for that: Bytecode is versioned and JVM checks if it supports the version it finds in . class files.
Is log4j 2.17 1 safe
1 can probably wait. A number of security professionals say that the latest vulnerability in Apache Log4j, disclosed on Tuesday, does not pose an increased security risk for the majority of organizations. As a result, for many organizations that have already patched to version 2.17.
Is log4j 2.16 still vulnerable
December 20, 2021
Log4j 2.17 has been released to address a Denial of Service (DoS) vulnerability found in v2. 16 and earlier. Log4j 2.16 and earlier does not always protect from infinite recursion in lookup evaluation, which can lead to DoS attacks. This is considered a High (7.5) vulnerability on the CVSS scale.
