Hi
I have found the cause this morning. The ContextClassLoader on the
currentthread was null. I managed to work around this by checking for null
and then setting it as the SystemClassLoader if needed.
I am using lein 2.5.3, java 1.8.0_65.
The ClassLoader issue only occurs on Mac, but there seem to be no other
examples of this online which suggest its specific to our setup. We are
using JavaFX, Clj, Cljs and Java.
I will continue to explore and see whether when we remove JavaFX dependency
in the next few months that resolves it.
For now, I have at least found a workaround.
