I am trying to install Owners plugin on Gerrit 2.11.5. Machine running the Gerrit instance has JAVA 1.7.0_67.
I compiled the plugin with the same Java version 1.7.0_67 and installed it on Gerrit. As soon as I query for open changes in web interface, I get "Internal server error" and get the following errors in the error_log.
Am I missing something here? Please give me some inputs.

I guess you're using the wrong version of the owners plugin ;-)
Where did you downloaded it from?
Luca.

mmm .... did you build it yourself? Or did you download it from somewhere? (e.g. gerrit-ci.gerritforge.com)
The "Unsupported major.minor version 52.0" means that it was built with Java 8.
Luca.

I initially had java 1.8. I changed the version of java to 1.7 and then built owners plugin.
:~> java -version
java version "1.7.0_67"
Java(TM) SE Runtime Environment (build 1.7.0_67-b01)
Java HotSpot(TM) 64-Bit Server VM (build 24.65-b04, mixed mode)
:~> javac -version
javac 1.7.0_67

You should have:
- Buck with Java7
- Java7
- a fresh clean build without using previous cache
... or if you want a plugin built without so much pain:
:-)

Thanks. Is the Plugin provided below compiled with Java 1.7?

HI Luca,
I don't think it is related to the javac version used to compile the plugin.
Just looking inside 2.11 stable branch there, reveals, that: gitective:
'io.fabric8:gitective-core:0.9.10',
is used: [1], but looking inside this JAR reveals, that it was built with Java 8:
$ javap -verbose -classpath gitective-core-0.9.10.jar org.gitective.core.BlobUtils | grep major
major version: 52
And this is not comptible with Gerrit 2.11.
Another build issue that this plugin seems to have: it depends transitively on the
plugin API, so that it produced 24 MB final artifact. I've sent you a fix, untested: [2].

How could the build be green then?
Are we then building it with Java 8 on the CI as well?

Yes, that is fixed on stable-2.13 and master.
However, it is not related to the Java 8 problem.

Hi Luca
I tried building the Owners plugin on 2.11.5 with JAVA 1.7.0_67 with the patch you provided[1]. Looking at the JAR files, I see few classes listing Major version as 52.0 and few as 51.0
$ file gerrit_owners/PRED_add_owner_approval_2_1.class
gerrit_owners/PRED_add_owner_approval_2_1.class: compiled Java class data, version 51.0
$ file org/gitective/core/BlobUtils.class
org/gitective/core/BlobUtils.class: compiled Java class data, version 52.0
