(I also had to fix the old, deprecated jflex grammars, because they got out of sync with java code)

> Key: LUCENE-6740
> URL: https://issues.apache.org/jira/browse/LUCENE-6740
> Project: Lucene - Core
> Issue Type: Improvement
> Reporter: Uwe Schindler
> Assignee: Uwe Schindler
> Labels: Java7, Java8
> Fix For: Trunk, 5.4
>
>
> This is a overview issue about improvements to reduce warnings during the build. Since we moved trunk to Java 8 and branch_5x to Java 7, there were introduced some additional warnings, mostly in generated code.
> ANTLR4 does automatically add the needed @SuppressWarnings, but jflex does not. There are also some rawtypes warnings, which changed in Java 7 (before Java 7 there were only "unsafe" warnings, now you need both.
> I enabled the Warnings tracker in Policeman Jenkins, we can therefore very easily check the warnings: e.g. on trunk: http://jenkins.thetaphi.de/job/Lucene-Solr-trunk-Linux/ (see diagram on the right), you can click on it, e.g. http://jenkins.thetaphi.de/job/Lucene-Solr-trunk-Linux/warnings4
