[undertow-dev] Cannot Add the alpn-boot jar to WildFly's Boot Classpath

[Tomaž Cerar]

Hey,

are you using proper version of apln-boot jar that applies to your exact
version of jdk?

Since 10.1, WildFly itself doesn't use the apln-boot hack anymore since,
but uses different solution in undertow that doesn't require patching jdk
classes.
