[JENKINS-67842] Issue while reading Jenkins.class bytecode level

added a comment - It seems that, if MasterBytecodeMajorVersionNumberGetter.get() succeeds in reading "jenkins/model/Jenkins.class" from the JAR file and parses int javaMajor from there, it then logs the value but discards it and proceeds to "Falling back to using Jenkins.getVersion to infer bytecode level". So the whole JAR-reading part could be deleted because it won't affect the return value anyway.
mario_b, until the bug with the path URL encoding is fixed, I think you can avoid it by uninstalling the Versions Node Monitors plugin, or by moving the Jenkins controller to a directory whose path does not contain spaces or other characters that would be encoded in URLs.

added a comment - It might be possible to use Jenkins.class.getResourceAsStream("Jenkins.class") instead of explicitly opening the JAR file.

added a comment - kon Thank you very much for your help. 
This looks like a bug in the Versions Node Monitors plugin. In the MasterBytecodeMajorVersionNumberGetter.get() method, URL.getFile() returns a path in which spaces have been encoded as %20, but JarFile(String name) does not expect that encoding.
