OGNL issues with java 16 and 17 about ognl HOT 9 CLOSED

Just to clarify, your error message on the top shows ognl-3.0.21.jar which means you are using OGNL 3.0.21 (an very old version). Are you sure you are running OGNL 3.2.1?

I would suggest switching to the latest version 3.3.2 which should address the problem -> #144 - also the problem with missing DefaultMemberAccess has been resolved in 3.2.19.

from ognl.

Hi, Lukaszlenart,

Yes, I am running ognl 3.2.1. And I tried 3.3.2 version... I read in a forum that DefaultMemberAccess was removed before 3.2.1 version. That is why I downgraded from 3.3.2 to 3.2.1.

The warning message while running versions 3.2.1 and 3.0.21 is the same using java 15. The reason it display 3.0.21 in the message is because I copied the message to report to you while running 3.0.21. I upgraded it later but I did not copy the message again.

But here is the message while running it with java 15 (ognl v3.2.1):

WARNING: An illegal reflective access operation has occurred
WARNING: Illegal reflective access by ognl.OgnlRuntime (file:/C:/Users/xxxx/WEB-INF/lib/ognl-3.2.1.jar) to method java.util.HashMap$Node.getValue()
WARNING: Please consider reporting this to the maintainers of ognl.OgnlRuntime
WARNING: Use --illegal-access=warn to enable warnings of further illegal reflective access operations
WARNING: All illegal access operations will be denied in a future release

And here the message while running it with java 15 and (ognl v3.3.2). the server can´t start:

What version of Struts do you use?

from ognl.

I´m using struts2-core 2.5.29
it's the last version.

from ognl.

I think you must wait for incoming Struts 6.0 (aka Struts 2.6) where a proper support for the latest Java has been already implemented.

That is good.
Is there any release date yet?

from ognl.

It should be soon, in 2-4 weeks
