This issue seems to be known by the jpype devs: Failure to start JVM with jpype 1.5.1 on Windows · Issue #1242 · jpype-project/jpype · GitHub
Let’s hope a new jpype version with a fix will be published soon, in the meantime you’ll have to stick to jpype 1.5.0.
I created a gitlab issue as well as a merge request which freezes jpype==1.5.0 in the orekit jpype dependencies.
