---------------------------------------
bq. FAILURE: Integrated in Struts-JDK7-pull-request #37
That jenkins/hudson fails seems like a configuration issue as the main part of
this patch must be applied to struts-annotation instead of struts itself.
When I try to build struts-core locally with this patch applied to
struts-annotation I get the following error with both jdk7 and jdk8. I must
admit that I have no idea what this whole apt stuff is about so I'm not able to
provide more help.

> JDK 8: build fails due to missing apt tool
> ------------------------------------------
>
> Key: WW-4402
> URL: https://issues.apache.org/jira/browse/WW-4402
> Project: Struts 2
> Issue Type: Bug
> Components: Build Management
> Affects Versions: 2.3.16.3
> Environment: JDK 8
> Reporter: Rene Gielen
> Labels: jdk8
> Fix For: 2.5
>
> Attachments: WW-4402-struts-core.diff, WW-4402.diff
>
>
> The generation of Struts Taglib TLD files relies on annotation processing
> with the apt tool, wrapped by maven-apt-plugin.
> In JDK 7 apt has been
> [deprecated|http://docs.oracle.com/javase/7/docs/technotes/guides/apt/GettingStarted.html]
> in favor of [JSR 269|https://jcp.org/en/jsr/detail?id=269]. In JDK 8 apt
> tool has been [removed completely|http://openjdk.java.net/jeps/117].
> In effect, Struts core and all tag library projects relying on the
> struts-annotation helper library won't build any longer under JDK 8. A major
> effort is needed to introduce a compatible replacement.
