-----------------------------------
Summary: Compilation error in ProcessFunctionTestHarnesses
Key: FLINK-34963
URL: https://issues.apache.org/jira/browse/FLINK-34963
Project: Flink
Issue Type: Bug
Affects Versions: 1.20.0
Reporter: Ryan Skraba
[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:
{code:java}
-------------------------------------------------------------
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
{code}
This is particularly curious because *e2e_2_cron_jdk17* with an identical build
step succeeds.
