[ClassCastException: java.nio.channels.ClosedChannelException cannot be cast to scala.collection.Seq]

I updated and switched to version 3 for JSON support and now I am having trouble running my existing code.

val auth = coreBroker.authenticatorsTable.filter(Map("authId" -> id)).run match {
    case Right(x) => if(x.size == 0) None else Some(x.head)
    case Left(x) => None
}

Please let me know if after switching I need to change something else. Thanks.

I'll push a fix for this, I actually never implemented the json serialization should of mentioned that in the readme lol. I'm fixing a few things I broke for the change-feed support so once I get that fixed and all tests pass I'll push an update.

[kclay]

Pushed new snapshot give it a try also you can do

val auth  = coreBroker.authenticatorsTable.filter(Map("authId" -> id))(0).toOpt 

[kclay]

Actually publish new version 0.4.4

[ohde]

Interesting, I pulled the latest and ensured Version 3 was being used, and I get the following at runtime:

I will continue to look into this error.

[ohde]

This is caused by: ERROR: this is the rdb protocol port (bad magic number) So I am looking at the compatibility of the driver with the db. Since I have not updated my database I will look at updating from 1.12 -> 1.13

[ohde]

Moving to new version has allowed me to use Version 3 and return results, however after results are returned it doesn't appear to be releasing it. Since, after so many requests I get no results returned. I will keep investigating.

[kclay]

Yeah Version 3 should work for 1.13+. And are you saying that after you query the connection isn't being released?

[ohde]

That is correct. I will write some Unit tests outside of my application for better testing/debugging of the issue at hand. However, all I have done is pulled and published the latest from your repo and in my application updated version2 -> version3, then updated to 1.13.4 of rethinkdb.

[kclay]

Great I'll test this out as well, I don't have any tests for the connection pool but I have an idea on why its not returning it.

[ohde]

I have confirmed this is an issue with the connection pool. As I have increased the max and now I am not getting the timeout issues as before when I run unit tests. Looking through implementation now in hopes of finding where the issue arises.

[kclay]

Sorry for the delay man been a crazy week. I'm working on reproducing this , let you know what I find. I'm wondering if you are getting any exceptions that are being hidden causing the connection to not return to the pool.

[kclay]

Ok test out 0.4.5-SNAPSHOT

[ohde]

No problem, today is the day I was going to take a look. I'm sorry I don't see any recent commits or releases in the repo.

[necrodome]

Are you going to release 0.4.5-SNAPSHOT?

[kclay]

@necrodome was released for 2.11 19days ago ,was waiting for confirmation from @maohde if it fixed his problem or not.

[ohde]

Crazy last few weeks. Works great, thanks.
