Search query for bugs in Apache Solr
Not long ago, we checked one of the most famous Apache projects, the NetBeans IDE. We found many interesting warnings issued by our analyzer during the check. By the way, the developers quickly noticed them and made a pull request before I did :) This time around, we've decided to take a look at another one of their big products, the Solr full-text search platform.

No SNAPSHOTs
Even ASF does not use Maven to build some of its projects anymore: Beam, Groovy, Lucene, Geode, POI, and Solr are not built with Maven. Those are not the most popular ASF projects, I know, but still, it is something.

Considerations for Unicode and Searching

Java string interpolation feature was cancelled
I guess you live in a more modern workspace than I do. I just picked a random open source project that (A) I know we use at work, and (B) I know is written in Java. I picked a random source file that sounded like it would have some mutable state, and the very first functions below the constructor were a trivial getter and setter around a private ivar.
https://github.com/apache/solr/blob/main/solr/core/src/java/...
I'm a little surprised it was in literally the first place I looked, but I'm not surprised that it was easy to find. "Use private ivars and write getters and setters to incapsulate your state" was probably the second thing that a generation of CompSci students learned in their first programming class, right after "an object is an instance of a class."
