Hi all, recently I'm trying to add a plugin to support Spring 6[1], which has a minimum requirement of Java 17 and Jakarta 9.
In order to compile our Java agent with the Spring 6 plugin, we have to set the baseline of the development JDK to 17, but we still keep the runtime baseline as Java 8 compatible. So this should only impact the experience of SkyWalking developer, not SkyWalking users. Another noteworthy thing I did in the pull request[1], is that, I've removed Powermock completely from skywalking-java repository and there is no reason we would bring it back in the future. I'll also try to remove it in the skywalking main repo. This is a future-prove work that would block us from upgrading the JDK baseline to Java 8+, or upgrading the Junit framework to Junit 5. So be careful when you review contributors' pull requests, if they bring Powermock back, don't approve to merge. [1] https://github.com/apache/skywalking-java/pull/444
