After upgrading to CA UIM 8.51, Java 8.0 is now the default version.
Likewise, in the archive, we can see java_jre 1.80.
However, there are certain probes that do not fully work with java_jre 1.80.
Currently these probes have been identified:
However, this could affect any Java-based monitoring probe that has not been updated since prior to March 2, 2017.
As it can be found in the sngtw's troubleshooting doc:
After upgrading to CA UIM 8.51, the probe stops processing tickets and displays an exception in the sngtw log file. This happens because the sngtw probe has not been updated to support Java Runtime Environment (JRE) version 8 and UIM 8.51 includes JRE 8.
Some probes' internal coding still need to be improved so they are not being affected while working with java_jre 1.80.
You must update the probe configuration to load JRE 7.
The above has been proved the resolution for the webservicemon probe as well.

Additionally, each probe has documentation for its respective software requirements.
Please consult the probe documentation:
and reference the Software Requirements for each probe in the "Release Notes" section for that probe.
