Dawid Wysakowicz commented on FLINK-13702: ------------------------------------------ What do you mean by ??invoke BinaryString.ensureMaterialized to make BinaryString read thread safe??. Actually I also spotted [FLINK-13740]. After a bit longer analysis I think adding a {{copy}} in the test is not enough. I am afraid the {{BinaryLazyFormat}} is really flawed in the current state and effectively unusable. I think we should aim to fix it in 1.10. > BaseMapSerializerTest.testDuplicate fails on Travis > --------------------------------------------------- > > Key: FLINK-13702 > URL: https://issues.apache.org/jira/browse/FLINK-13702 > Project: Flink > Issue Type: Bug > Components: Table SQL / Planner > Affects Versions: 1.10.0 > Reporter: Till Rohrmann > Assignee: Dawid Wysakowicz > Priority: Critical > Labels: test-stability > > The {{BaseMapSerializerTest.testDuplicate}} fails on Travis with an > {{java.lang.IndexOutOfBoundsException}}. > https://api.travis-ci.org/v3/job/570973199/log.txt -- This message was sent by Atlassian Jira (v8.3.4#803005)
