Description

We are upgrading one of our project to Struts 2.5.12. My project setup is as mentioned in the link: https://stackoverflow.com/questions/45347478/struts2-5-12-npe-while-using-gettext-method-from-actionsupport

When I try to submit request to action on the first page, I see NullPointerException as below. Debugged it and found that textProviderFactory is null. Tried it a several times and I see that it is intermittent. Approximately twice in 10 server restarts the textProviderFactory is initialized.
Could you please check if I am missing any configuration? I have raised a stackoverflow for this, but haven't got any response yet - https://stackoverflow.com/questions/45483364/struts2-5-12-npe-in-deligatingvalidatorcontext
