Scenario test failures with Java 8 and 11 #660

bestbeforetoday commented 9 months ago

From early November 2023, scenario tests run with Java 8 and Java 11 have begun to fail with the following errors:

Error:  Chaincode event listening.Chaincode event listening - Close does not interrupt other chaincode event listeners -- Time elapsed: 30.54 s <<< ERROR!
java.lang.NullPointerException: timeout waiting for event

Frequency of errors has increased over time and as of late November 2023 these scenario tests (only with Java 8 and Java 11) are consistently failing.
