The unit tests in binding-erlang-runtime hang if the current version of Erlang/OTP is in the path.
The binding runtime code and unit tests were originally developed with version R12B of the Erlang/OTP runtime and version 1.4.2 of the jinterface jar (the Java/Erlang bridge). When run with this combination, the unit tests complete successfully.
Making either or both of the following changes causes the unit tests to hang:
1. Upgrading the Erlang/OTP runtime from version R12B to the current version R14B.
2. Upgrading the jinterface jar from version 1.4.2 (com/ericsson/otperlang-1.4.2.jar) to the current version 220.127.116.11 (org/erlang/otp/jinterface-18.104.22.168.jar).
This implies that there is some code in binding-erlang-runtime that requires the older version of the Erlang/OTP runtime and/or the older version of jinterface.
