Lukasz Lenart commented on WW-5513:
-----------------------------------
There is one problem with releasing a new 6.x version with the latest OGNL
version. The Struts OVal plugin depends on the older version of OGNL and it
isn't possible to upgrade it. I can remove the plugin and then perform the
upgrade to OGNL 3.5.x
> Struts 6.4.0 performance issue in jdk 21

> Key: WW-5513
> URL: https://issues.apache.org/jira/browse/WW-5513
> Project: Struts 2
> Issue Type: Improvement
> Reporter: Alireza Fattahi
> Priority: Major
> Fix For: 6.8.0
>
>
> We face performance issues on `Struts 6.4.0` when switch from `jdk 1.8` to
> `jdk 21`. It seems that the OGNL needs to be upgraded to new version and
> remove the dependency to java `SecurityManager` . Please see:

> My question is that will be a `Struts 6.x.x` release which work with `OGNL
> 3.5.x` and `JDK 21` ? This will be a great help as it will break down the
> migration step in two distinct ones:
> 1. First we will upgrade to `JDK 21` on `Struts 6` ( Make sure every thing
> works with `JDK 21` )
> 2 Second we will upgrade to `Struts 7`. It seems (at least in our project)
> migrating from `Struts 6` to `Struts 7` needs high accuracy.
