ElasticSearch + Node on Mac OS X Yosemite: JRE crash?

Question

Somewhat baffled by this one, probably because I haven't often encountered a JRE core dump.

I'm using the official ElasticSearch module for Node.js, and attempting to create a new document in one of my indices.

My Node app appears to connect to the ES instance just fine, but when I execute the create request, my JRE bites the dust! Here's the error spit out by Node:

Elasticsearch INFO: 2015-12-16T21:40:47Z
  Adding connection to http://my.server.address/:9200
Elasticsearch DEBUG: 2015-12-16T21:40:53Z
  starting request { method: 'POST',
    path: '/test/document',
    body: { foo: 'bar' },
    query: { op_type: 'create' } }

It looks like there's a bug with a console.log() statement causing this in node 5.2.0: http://github.com/nodejs/node/issues/4261

If you downgrade to Node 5.1.1, you should be good to go.
