AFAIK, nobody has fixed the issue. The problem is related to the
"feature" of Mac OS X where UI event loop can only run in the primary
thread (blame Apple for that). References like [1] on the web seem to
indicate that the JVM needs to be started in a separate thread. But
someone has to actually implement it and test it.

All the data continuously generated in your IT infrastructure
contains a definitive record of customers, application performance,
security threats, fraudulent activity, and more. Splunk takes this
data and makes sense of it. IT sense. And common sense.
