<satire> I had some performance issues, so I decided to update core Lucene code. Now I have 3 problems: *) performance issues *) hard to debug code *) annoyed Solr developers whose use cases I did not consider
Not that I am reading random JIRAs or anything..... </satire> Seriously though, for those trying to step-through the code, it might be worth checking out something like Chronon http://chrononsystems.com/, https://www.jetbrains.com/idea/help/debugging-with-chronon.html . I played with it as part of IntelliJ Ultima plugin (no extra charge) and it was quite interesting. Though when a plugin, it has to start Jetty/Solr in-process, which might be harder (but not impossible) with Solr 5. I am hoping to revisit and blog about how to do that at some point soon.
