Downgrade from Java OpenJDK 64-Bit Server VM 1.8.0_292

Good morning, I have an application that works only with Java OpenJDK 64-Bit Server VM 1.8.0_292, however we are in the Java OpenJDK 64-Bit Server VM 1.8.0_312 version. How can I install it?

Answer

1. Go here: https://adoptium.net/releases.html?variant=openjdk8

2. download package

3. extract package

4. try calling it direclty (/new/path/jdk8/bin/java -version). This should now differ from calling the default java (java -version)

5. instead of calling the first java the systems finds (like java -Xmx500G -jar yourApp.jar), run your app via direct java path call: /new/path/jdk8/bin/java -Xmx500G -jar yourApp.jar

6. For Windows you can create .bat files, for linux you can create runnable bash scripts etc.

Oh, and a little side note: if that app is really only running under a certain revision version of java, it’s probably really bad software…
