# Detailed description
Unable to invoke lambda function compiled in java 11. Localstack latest image still shows java version 8.

## Expected behavior
Should be able to invoke lambda function compiled in java 11.

## Actual behavior
Getting error-
Exception in thread "main" java.lang.UnsupportedClassVersionError: publisFunction has been compiled by a more recent version of the Java Runtime (class file version 55.0), this version of the Java Runtime only recognizes class file versions up to 52.0

# Steps to reproduce

docker-compose up -d
Create lambda function
Create SQS 
map lambda and sqs
send message to SQS to invoke lambda

Similar issue was reported #2093.  Couldn't find the answer if that was fixed and latest image of Localstack should compile in JAVA 11.
