Support for java 10

[krilak]

While trying to compile our project that uses egen using java 9/10, the following warning message was observed-
warning: Supported source version 'RELEASE_8' from annotation processor 'com.devexperts.egen.processor.AutoSerializableProcessor' less than -source '1.9'
warning: Supported source version 'RELEASE_8' from annotation processor 'com.devexperts.uilocalizer.LocalizableProcessor' less than -source '1.9'

This could also be a contributing factor to causing javac itself to fail (See exception below). We can see that AutoSerializableProcessor (which is currently at SourceVersion 8) also uses com.sun.tools.javac.tree.JCTree which could be causing the exception.-

An exception has occurred in the compiler (9.0.4). Please file a bug against the Java compiler via the Java bug reporting page (http://bugreport.java.com) after checking the Bug Database (http://bugs.java.com) for duplicates. Include your program and the following diagnostic in your report. Thank you.

The problem reported for compiler version 9.0.4 that is already superseded with version 10.
Do you have the same problem with version 10?
Can you provide a simple example of code that would demonstrate the problem for Java 10?

Yes the Error happens with Java 10 as well. Please see attached.

[tsitelov]

Thank you for the confirmation. What about a sample code that would reveal the error?

Hi Dmitry, I'm trying to compile egen from source but I'm having issues as my maven settings for some reason cannot download the artifacts, both from https://repo.maven.apache.org/maven2 as well as bintray related (http://dl.bintray.com/devexperts/Maven). Could you do the following a) confirm that you can compile egen on Java 10 b) send a zipped folder containing all the dependencies for the egen project, either through email or shared drive etc. as it will be faster than diagnosing any maven/network/ proxy issues on my machine.

I confirm that current version of egen itself can be compiled with Java 10 with following minor changes (at least it works for me):
