Fwd: Struts 7.0.0 - JSP rendering is taking 3X time compare to struts 6.3.0.2

Hi

After upgrading to version 7.0.0, the JSP rendering time has significantly
increased from around 500ms to approximately 1.5 seconds. Upon further
investigation, it was discovered that the increase in time is primarily due
to Ognl.getValue taking longer than it did in the previous version.

Sample JSP & Java Code as below:

We have added following constant in struts.xml

<constant name="struts.chaining.copyErrors" value="true" />
<constant name="struts.chaining.copyMessages" value="true" />
<constant name="struts.ui.checkbox.submitUnchecked" value="true"/>
<constant name="struts.ognl.expressionMaxLength" value=""/>
<constant name="struts.parameters.requireAnnotations" value="false"/>
<constant name="struts.allowlist.enable" value="false"/>
<constant name="struts.mapper.alwaysSelectFullNamespace" value="false"/>
<constant name="struts.actionConfig.fallbackToEmptyNamespace" value="true"/>

Can you please help with this ?
