Re: [xep-support] java.lang.NoSuchMethodError calling XEPTask

Hello Christopher,

I've just realized that we haven't commented on this. This really
looks like a JVM problem because it happens deep in compiled code and
this method does exist. Try to use different Java build. You may
upgrade XEP as well (just in case).

Best regards,
