@synhershko @guidotag I just setup Lucene 4.8 on my local with source code
and IDE so that I can debug (some of those multithreading bugs are brutal to
catch otherwise), and can confirm that in Java version, FSDirectory does not
create the directory, it only says that it does in the comment. If you look at
the code, it make sense:
https://github.com/apache/lucene-solr/blob/lucene_solr_4_8_0/lucene/core/src/java/org/apache/lucene/store/FSDirectory.java#L128
There is no explicit create being called, and constructing a File class
with a path does not create a file that represents such a path. When the port
was being done, whoever read that comment for "getCanonicalPath" that said
"creating it if it doesn't exist." simply got mislead.
