Steps to Reproduce

The "short" insert method for date values (without delimiters, e.g. 04112022) will convert the value into a wrong date. The behaviour depends on the JAVA version used in Apache Tomcat (e.g. Eclipse Adoptium and Oracle). It is working as expected for  Oracle 1.8.0_291, OpenJDK Temurin 1.8.0_345. But, not working as expected for Adoptium 11.0.7.10, 11.0.13.8, 11.0.17.8.

Insert "04112022" in the DATE field and press TAB to leave it.

You have only to change the "JAVA Virtual Machine" in the Apache configuration and restart the Apache to reproduce it.

Current Result

With the JAVA version from Adoptium, the numbers will convert WRONG to "04.11.02".
(tested with version 11.0.7.10, 11.0.13.8, 11.0.17.8)

With the JAVA version from Oracle or Temurin, the numbers will convert CORRECT to "04.11.22".
(tested with version Oracle 1.8.0_291, OpenJDK Temurin 1.8.0_345)

Expected Result

The above date should be converted to something like 04.11.22 or 04.11.2022

Workaround

Set Java option in Tomcat -
-Djava.locale.providers=COMPAT
