There is no plan to release 5.5.2, development has moved to trunk and 6.x. Also, while there is a patch for that JIRA it hasn't been committed even in trunk/6.0.
So I think your choices are: 1> find a work-around 2> see about moving to Solr 6.0.1 (in release process now), assuming that it solves the problem. 3> See if the patch supplied with SOLR-8940 works for you and compile it locally. 4> agitate for a 5.5.2 that includes this fix (after the fix has been vetted).
