> Having recently started using JSON based logging, I noticed that in many code 
> paths situations where an error involving a "Throwable"  are logged isn't 
> happening correctly (This is also noticeable using the default solr 
> log4j2.xml configuration - but only subtly)
> The problem is that {{SolrException.log(...)}} has some very old (pre Solr 
> 1.0, certainly pre SLF4j/Log4j) and hackish logic/code in it to support 
> {{SolrException.ignorePatterns}} (which was designed for tests that wanted 
> "quieter" output when they were intentionally triggering error situations.  
> This logic "stringifies" the entire Throwable (including stack trace) to test 
> against any {{ignorePatterns}} that exist (even if there are no ignore 
> patterns) before handing the resulting string off to the 
> {{loggger.error(...)}} call -- _as a log message string_ - w/o the normal 
> "structure" context of the original Throwable instance.
> This causes the full exception stack trace to come through as the log 
> "message" -- even in log appenders that have been configured to only log 
> partial stack trace details, or log them in special fields (ie: JSON Logging)
