Struts2 configuration (struts.xml) and Convention Plugin not
compatible with Java 8?
Hi all,
does anyone know
if this these exceptions [1][2] i see when staring application
are the result of using lambda expressions inside actions?
If i just move these lambdas out of action body
to another class (helper)
everything works just fine.
How can i help to resolve this?
I would love to have lambdas in action methods.
Struts version is 2.3.16.3
Java version is 1.8.0_05
Best greetings,
Paweł Wielgus.

It can be part of 2.3.x as well, the plan is to be compatible with
JDK8 but not depend on it. Lambdas are implemented as anonymous
classes as far I can recall, so maybe improving ClassFinder in that
area would do the trick ;-)

Re: Struts2 configuration (struts.xml) and Convention Plugin not
compatible with Java 8?
Posted by Paweł Wielgus <po...@gmail.com>.
Hi Łukasz,
can i somehow help with this?
Is it all about classloader black magic
or a normal programer can make any progress with this subject.
I understand that JDK8 is much more than just lambdas,
so maybe i would be able to help with this "lambdas only" problem.
I would be happy if S2.3.x would be abble to load such action classes
but would not be fully compatible with JDK8.
But maybe this is all or nothing case?
Best greetings,
Paweł Wielgus.

S2 isn't JDK8 compatible, it will be case for S2.5
