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

## Actual behavior
Getting error-

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