java.lang.NoSuchFieldError: EXT_ALPN

[ghost]

I am triying to run Pushy on windows with tomcat 8 and Oracle 1.8 with Jetty's ALPN implementation. It gives me a very rare error and I can not find information about it. I have spend several days but nothing works.

When i try to init Pushy my console ouput is:

Thanks in advance

How, exactly, are you using Jetty's ALPN implementation? Are you adding alpn-boot to your boot classpath manually, or are you using something like alpn-agent? It sounds to me like you may have a version mismatch between alpn-boot and your JDK.

I am adding alp-boot to boot classpath manually. I am trying different versions of alpn-boot but nothing works. My java version is Oracle 1.8u66 in this case my alp-boot version should be 8.1.6.v20151105 according to http://www.eclipse.org/jetty/documentation/9.4.x/alpn-chapter.html. I am using Oracle JVM but this website always says about Open JDK versions. Is it important in this case?

Thanks for your fast answer :)

For Science™, would you mind trying alpn-agent instead of going directly for alpn-boot?

[jchambers]

One other thought: are you using a non-standard crypto provider?

@carlosDialcom I'm going to close this for now due to a lack of activity. It sounds like nobody else is having this problem, and I can't reproduce it. Please do leave a comment here if you get a chance to investigate further and we'll happily re-open the issue. Thanks!
