User configured AWS_LAMBDA_MAX_CONCURRENCY

[wilsonrf]

Hi,

Since I updated to the latest version of the aws-lambda-java-runtime-interface (2.8.0) I have multiple log messages like this:

User configured AWS_LAMBDA_MAX_CONCURRENCY is not valid. Please make sure it is a positive number more than zero and less than or equal 1000
java.lang.NumberFormatException: Cannot parse null string
...
Defaulting to no concurrency.

We're seeing the same thing. We'll get a burst of lambda failures over a 20-minute period and then it goes away. They all have that same message.

This is fixed in v2.8.2.
