Happens on Linux when trying to build Eclipse plugins of RCPTT Runtime.
Comment 2 Andrew Clement CLA 2018-08-24 21:05:55 EDT 
Are you possibly passing a classpath with a jrt-fs.jar entry when working on a JDK less than 9?  I can imagine that would cause this. Rather then ignoring jrt-fs.jar we assume you passed it because you are working on Java9+ and attempt to use the JDK to work with it - if the JDK is in fact Java8 or lower we will not find those JDK classes and I think that could cause initialization problems in JImageEntry.
Comment 3 Andrew Clement CLA 2018-10-11 14:22:02 EDT 
Actually I see what could be happening here, it is perhaps because the filesystem initialization is done in static initialization of the class rather than when actually required. Changed it around.
