Alireza Fattahi commented on WW-5513:
-------------------------------------
The minimum version for struts 7.0 is `jdk 17`:
[https://cwiki.apache.org/confluence/pages/viewpage.action?pageId=332499966#VersionNotes7.0.0-InternalChanges]
and we are still at `1.8`.
On the other hand I also think that `jdk 17` also have same performance issue
as `SecurityManager` ( which seems to be the source of this problem) is
deprecated in `jdk 17` too.
Any way, this fix
"https://issues.apache.org/jira/projects/WW/versions/12355542"; will be a great
help !
> Struts 6.4.0 performance issue in jdk 21

> Key: WW-5513
> URL: https://issues.apache.org/jira/browse/WW-5513

> Issue Type: Improvement
> Reporter: Alireza Fattahi

> 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:
> [https://github.com/orphan-oss/ognl/issues/347]
> [https://github.com/orphan-oss/ognl/milestone/2]
> 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.
