             Summary: SolrCLI can swallow all information about an exception from a request to Solr
                 Key: SOLR-12206
                 URL: https://issues.apache.org/jira/browse/SOLR-12206
             Project: Solr
          Issue Type: Improvement
      Security Level: Public (Default Security Level. Issues are Public)
          Components: scripts and tools
    Affects Versions: 7.3
            Reporter: Shawn Heisey
            Assignee: Shawn Heisey


User got an NPE when trying to create a core, no useful information:

{code}
$ /usr/local/solr/bin/solr create -V -c new_core

WARNING: Using _default configset with data driven schema functionality.
NOT RECOMMENDED for production use.
         To turn off: bin/solr config -c new_core -p 8983 -property
update.autoCreateFields -value false
Exception in thread "main" java.lang.NullPointerException
	at org.apache.solr.util.SolrCLI.getJson(SolrCLI.java:731)
	at org.apache.solr.util.SolrCLI.getJson(SolrCLI.java:642)
	at org.apache.solr.util.SolrCLI$CreateTool.runImpl(SolrCLI.java:1773)
	at org.apache.solr.util.SolrCLI$ToolBase.runTool(SolrCLI.java:176)
	at org.apache.solr.util.SolrCLI.main(SolrCLI.java:282)
{code}

Looking at the code, this happened because SolrCLI got a ClientProtocolException in its call to HttpClient, but that exception did NOT have a message string attached, so when the code in the catch block tried to look at the message, it threw NPE.
