JVM crash log

This crash happened while using Eclipse Mars.1 which had:
- a markdown editor tab showing the Preview view (web-like); the markdown has no javascript
- a web browser tab open on:
<a href="http://www.brpreiss.com/books/opus8/html/page96.html#SECTION004300000000000000000">http://www.brpreiss.com/books/opus8/html/page96.html#SECTION004300000000000000000</a>

Eclipse was running with:
java version &quot;1.8.0_51&quot;
Java(TM) SE Runtime Environment (build 1.8.0_51-b16)
Java HotSpot(TM) 64-Bit Server VM (build 25.51-b03, mixed mode)
from jdk-8u51-linux-x64 downloaded as a tarball from the web.

The log says:

Core dumps were disabled, so I don't have any.

If this is insufficient to investigate, feel free to close as unreproducible.  This is the first time I encounter this crash.

Thanks!
