@AlenBadel @dchopra001 @harryyu1994 - let's triage this please.

[harryyu1994]

Okay, starting a grinder to determine failure rate. (50/50 passed so far) . I noticed it says "Error: A JNI error has occurred, please check your installation and try again", not sure how JNI works but could be just a machine/test setup issue?

[gacholio]

That's a generic error from the launcher if it encounters an exception during startup.

[pshipton]

@smlambert @Mesbah-Alam have you seen this type of failure before?

[harryyu1994]

Grinder so far: 150/150 passed

[smlambert]

I do not recall seeing this particular error before.

[pshipton]

Will close as some kind of not understood machine/test setup issue, and can re-open if it shows up again later.

[Mesbah-Alam]

I have not seen this error before.
