This is still an issue. I was able to determine that it is directly related to the Java 64-bit client. When running a Minecraft Server from Java 32-bit, this issue does not occur.
Also, the server starts fine, it crashes when any client attempts to connect.
This was tested on Java 7_80 and Java 8_51
Below is the crash log I receive every time:
