Steps to reproduce

1. Create a new form with one Text Field.
2. Add validation for that field. It must contains the text "F"
3. Save the form.
4. Deploy Forms portlet and select previously created form.
5. Type the text "1234F"

Expected behavior
There's no validation error since the text 1234F contains the subtext "F"

Actual behavior
There's a validation error.
