hikari-java6: NoSuchMethodError ScheduledThreadPoolExecutor.setRemoveOnCancelPolicy

[manikantag]

Hi,

I've upgraded from 1.40 to hikari-java6 2.0.0, and I m getting below exception at server start up:

This method is not available in Java 6, it is only present from Java 7 (comparison between JDK_7 and JDK_6)

Is there anything I should be knowing? or this needs some fix? Similar issue reported here

I m using Hikari from last 4-5 months and I m very much pleased with the direction it is heading.

Thanks.

No, this looks like a legitimate bug. 2.0.0 is unannounced, but a really appreciate that you checked it. I will put out a 2.0.1 release today. If that runs without issue, I will announce the release.

[manikantag]

That's fast! I'll update to 2.0.1 and will let you know. Thanks.

[brettwooldridge]

Did it work? I'm waiting to announce the release on Twitter until I have your confirmation.

[manikantag]

Just tested. Now server started, without any exceptions & working fine. Thanks for the quick fix.

Also, it would be more clear for starters if you mention the module separation and their Java requirements and latest versions in Github project page. Ex: Maven artifact snippet still refers old 1.3.8 version.

[brettwooldridge]

Already done in the past hour. 😸

I m talking about the project page, not the Readme file. I mean this: http://brettwooldridge.github.io/HikariCP/

[brettwooldridge]

Ah yes, I'll get to that tonight.

Thanks.
