Jakob Furrer commented on SOLR-5532:
------------------------------------
Thanks for looking into this issue so fast.
And my apologies for being very sloppy in the bug description.
Due to time constraints, I did not test the code provided above in a standalone
setting.
I am aware that this is a big no-no. Mea culpa.
I only now figured out that setting the XMLResponseParser triggers the Exception
{code}
solrServer.setParser(new XMLResponseParser());
{code}
Setting the BinaryRequestWriter or not does not influence the result for me.
Side-Question:
The XMLResponseParser is set in my custom application since very long. I cannot
recall when or why set that specific parser.
Could anyone give my some information whether, when or why this parser should
(not) be set?
As for
{quote}
A global search for "charset=UTF-8" on the source code of solrj indicates that
other functions besides "ping" might be affected as well, because there are
several places where "application/xml; charset=UTF-8" is spelled without a
space after the semicolon.
{quote}
I am not familiar with the Solr sourcecode at all. I saw these search results,
where "; charset=utf-8" appears 62 times and ";charset=utf-8" appears 12 times.
>From that I conclude that there is an inconsistency how to spell this encoding
>type within this library.

> HttpSolrServer does not accept content type of "ping" response
> --------------------------------------------------------------
>
> Key: SOLR-5532
> URL: https://issues.apache.org/jira/browse/SOLR-5532
> Project: Solr
> Issue Type: New Feature
> Affects Versions: 4.6
> Environment: Windows 7, Java 1.7.0_45 (64bit), solr-solrj-4.6.0.jar
> Reporter: Jakob Furrer
>
> I just upgraded my Solr instance and with it I also upgraded the solrj
> library in our custom application which sends diverse requests and queries to
> Solr.
> I use the "ping" method to determine whether Solr started correctly under the
> configured address. Since the upgrade the ping response results in an error:
> {code:xml}
> Cause: org.apache.solr.client.solrj.impl.HttpSolrServer$RemoteSolrException:
> Expected content type application/xml; charset=UTF-8 but got
> application/xml;charset=UTF-8.
> <?xml version="1.0" encoding="UTF-8"?>

> {code}
> The Solr application itself works fine.
> Using an older version of the solrj library than solr-solrj-4.6.0.jar (e.g.
> solr-solrj-4.5.1.jar) in the custom application does not produce this error.
> The Exception is produced in a Code block (_HttpSolrServer.java_, method
> _request(...)_, around. line 140) which has been introduced with version
> 4.6.0.
> Code to reproduce the error:
> {code:xml}
> try {
> HttpSolrServer solrServer = new
> HttpSolrServer("my-solr-application-address");
> solrServer.ping();
> } catch (Exception e) {
> e.printStackTrace();
> }
> }
> {code}
> A global search for "charset=UTF-8" on the source code of solrj indicates
> that other functions besides "ping" might be affected as well, because there
> are several places where "application/xml; charset=UTF-8" is spelled without
> a space after the semicolon.
