java.nio.ByteBuffer.flip()

[fcorneli]

Atmosphere version: 2.7.14 Java version: 8 We get the following exception:

15:21:08,709 ERROR [org.atmosphere.cpr.AsynchronousProcessor] (nioEventLoopGroup-3-5) : java.lang.NoSuchMethodError: java.nio.ByteBuffer.flip()Ljava/nio/ByteBuffer;
    at org.atmosphere.client.TrackMessageSizeInterceptor$Interceptor.transformPayload(TrackMessageSizeInterceptor.java:173)

This did not happen on Atmosphere versions 2.7.10, 2.7.11.

I guess:

((Buffer) bb).flip();

should do the trick?

[jfarcand]

Thanks. When I look at gitblame, I don't see recent changes...

Digging!

[jfarcand]

Ah got it. The release has probably been made using jdk 21.

[fcorneli]

Yep. Was just also thinking about this... :)

[jfarcand]

@fcorneli Do you need a new release? I was waiting for a fix or two before re-releasing using jdk8

[fcorneli]

@jfarcand Not urgent from our side.

[fcorneli]

@jfarcand Any news on a release?

[jfarcand]

@fcorneli Today and at worse, tomorrow!
