Hi Carl,
Thank you for your detailed message.
It's a bug in the EnvUtil class which wrongly assumes that the
classloader for the EnvUtil class cannot be null. However, per the
javadocs of the Class.getClassLoader method:
Some implementations may use null to represent the bootstrap class
loader. This method will return null in such implementations if this
class was loaded by the bootstrap class loader.
Could you please file a jira issue report for this bug? A github pull
request would also be appreciated, although not strictly necessary.
