------------------------------------
Summary: Compiling error in WindowOperatorTest with JDK11
Key: FLINK-23982
URL: https://issues.apache.org/jira/browse/FLINK-23982
Project: Flink
Issue Type: Bug
Components: Build System
Affects Versions: 1.14.0
Reporter: Xintong Song
Fix For: 1.14.0
What I don't understand is, while the error does not seem to be environment
related, the other JDK11 compiling stages in the same build did not fail.
