We are receiving following error when upgrading java-1.8.0-openjdk-1.8.0.232.b09-0.el7_7.x86_64.rpm to java-1.8.0-openjdk-1.8.0.242.b08-0.el7_7.x86_64.rpm

Downgrading java is a workaround for now.

This is due to a fix in JDKs starting from version 1.8u242. See issue JDK-8230967 in the release notes:

https://www.oracle.com/technetwork/java/javase/8u241-relnotes-5813177.html

As a quick fix I already provided a pull request for a dirty workaround. This doesn't really fix the issue but at least it makes ghost4j work again with newversion of Java:
