[Bioc-devel] Unable to reproduce OS/X build error for "netDx" package

Hi BioC community,
My package relies on a Java jar and detects whether the OS has Java 8 or
11, to be accordingly compatible. I can't seem to resolve the build error
on the BioC Mac system; the error message is a symptom of Java 8
incompatibility.

However, on my 2014 Mac Air which runs Java 8, the offending example
("Predict_CaseControl_from_CNV.Rmd") runs through to completion. What is
the issue here? It would be great to have all operating systems building
successfully.

Details below. Thanks!
