Looking for assistance from Google Cloud infrastructure team for the
following issue.
We started seeing failures with two of our file upload servlets hosted in a
Google App Engine project,
at about 5:50 PM Pacific Time Wednesday night, September 5, 2018.
We did NOT do a new deployment recently, so code is the same as what was
working shortly before that.
This is the server error we are seeing now:
java.lang.VerifyError: Operand stack overflow
Reason:
Exceeded max stack size.
