New Java 7 Dependancy about docker-plugin HOT 7 CLOSED

This seems to be getting pulled in from jDocker which is getting pulled in from:
java.lang.UnsupportedClassVersionError: org/glassfish/jersey/client/proxy/WebResourceFactory : Unsupported major.minor version 51.0

The jDocker README is also out of date claiming Java 1.6 compatibility.

from docker-plugin.

I meet same problem, it works ok for 0.3.5 with Java 1.6. Do you have plan to support Java1.6 again, or will stay with Java 7 ?

I have submitted a pull request that restores Java6 compatability: nirima/jDocker#2

from docker-plugin.

So 1.7 is required for any Jersey version >= 2.7 (current release is now 2.9).

When diagnosing why the API was failing (which seemed eventually be that the version of docker I was testing against returned a content-type header, but no actual content), the first course is usually to upgrade dependencies.

Whilst it's probably possible to revert backwards in this instance, there isn't a 1.6 maintenance version for Jersey from what I can see.

I used to be somewhat more sympathetic to Java versioning when it wasn't open-source, and significant platforms (like Macs) were perennially a version behind. That's not true any more; Java 1.6 was EOL over a year ago, 1.7 will EOL in under a year, and the roadmaps that state when these events happen have been around a long time.

What seems to happen however is that Corporate IT departments are slow to upgrade. They want their free software to run, without doing any work themselves. My worry is that by bowing to requests to maintain compatibility with obsolete platform versions, we're actually rewarding that behaviour - and making it even harder to move the platform on and take advantage of modern platform features.

From the sound of an email response on the Jenkins list (https://groups.google.com/d/msg/jenkinsci-users/QCOzryzieeo/l9VZUul1U2EJ) it sounds like it is expected that plugins continue to support Java 6. Not sure if thats official guidelines or not but perhaps if there is a way to do so the plugin should?

Just noticed that Java 6 compatiblity has been restored so ignore my previous comments :) Presumably this issue can be closed now?

from docker-plugin.

I've updated to 0.6.1 and appears to be working with Java6. Closing.
