Alexis Midon commented on ODE-549:
----------------------------------
For the first exception, I think I nailed down the issue:
for the first invocation, thread A has detected that the options need to be
initialized and has started to do it. A second invocation happens in thread B
which reads the reference but the reference is still null because thread A is
not done initializing it.
A (read/write) lock on the options ref should fix this issue.
