[jira] [Commented] (FLINK-14093) Java8 lambdas and exceptions lead
to compile error
[ https://issues.apache.org/jira/browse/FLINK-14093?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16932061#comment-16932061 ]
TisonKun commented on FLINK-14093:
----------------------------------
[~zhaoshijie] We cannot just introduce the workaround without any context. Following contributor is likely to revert your commit regarding as improvement. For whether or not to tolerate JDK bugs, I think you'd better start a discussion thread on dev mailing list. We need to reach a consensus before start any code working.

> if using Java 1.8.0_102 to compile, it build success. it maybe a case of bug [JDK-8054569|https://bugs.openjdk.java.net/browse/JDK-8054569], although we can fix this by upgrading the JDK,but i think it is better of compatible with different versions of the JDK8.
