For Perceptive Content customers using an ANSI database and running Java 21, updates to Java's date handling may cause timestamp fields to be formatted with incompatible Unicode characters.
To avoid issues with date‑formatted form fields, configure the Form Server Tomcat JVM with the following option:
-Djava.locale.providers=COMPAT,SPI
This setting restores compatibility behavior, allowing timestamp fields to function correctly without requiring changes to the form XML or the database schema to support Unicode characters.
