I'll stand corrected with the versions of java, it's obviously not my thing, but simply put, I've never *ever* had openjdk work properly for anything Java that wasn't specifically built in openjdk. I just don't bother with it usually as most everything is typically built/tested around Oracle and Oracle only. This proved itself true last week firing up JBidwatcher on this system, only had openjdk, and wouldn't even launch with it. I had to put oracle java on it to work still. Most enterprise java apps I have seen in use in businesses require specific, usually outdated/insecure versions, never get updates because they break the apps, and rarely work on anything but the platforms they were built on, so I call bullocks on the compatibility play. It sounds great in theory, but every practical application I've seen in use in enterprise ended up a bloody mess. Much like Flash now, it's just a zombie that won't die, but should imho. -mb On Mon, May 4, 2020 at 10:33 PM Joseph Sinclair via PLUG-discuss < plug-discuss@lists.phxlinux.org> wrote: > Sorry, Michael, but this is complete bunk. > > On 2020-05-04 11:29 AM, Michael Butash via PLUG-discuss wrote: > > Again OpenJDK and OracleJRE are totally different - including version > > numbers.
