Lukasz Lenart commented on WW-4706:
-----------------------------------
JDK9 isn't officially released so it won't be supported. Also the latest beta
builds are missing some classes and Struts2 won't work on those builds. Also
2.2.x branch even won't work on JDK8, you should migrate to 2.3.21 and then use
the Java 8 plugin [1] or migrate to 2.5.5 and then it works natively.

> It looks like the asm boundle with struts 2.2.1 does not support jdk9. Is
> this true? I replaced the libs of the struts2.2.1 jars with struts2.3.31
> jars. The tomcat9 and jetty9.3 still throw exception.
> Could you confirm is struts2 support jdk9? If not, which version of struts
> support jdk9?
