Description

 

https://dev.azure.com/apache-flink/apache-flink/_build/results?buildId=58627&view=logs&j=64debf87-ecdb-5aef-788d-8720d341b5cb&t=f041a596-2626-58e5-69fa-facfbaf86c0f&l=6435

At the compile step in e2e_1_cron_jdk17 / Build Flink step:

-------------------------------------------------------------
00:24:17.239 [ERROR] COMPILATION ERROR : 
00:24:17.239 [INFO] -------------------------------------------------------------
00:24:17.239 [ERROR] /home/vsts/work/1/s/flink-streaming-java/src/test/java/org/apache/flink/streaming/util/ProcessFunctionTestHarnesses.java:[55,54] incompatible types: cannot infer type arguments for org.apache.flink.streaming.util.OneInputStreamOperatorTestHarness<>
    reason: inference variable IN has incompatible equality constraints OUT,IN,IN
00:24:17.239 [INFO] 1 error

This is particularly curious because e2e_2_cron_jdk17 with an identical build step succeeds.
