Illegal access: this web application instance has been stopped

[org.apache.xerces.jaxp.datatype.XMLGregorianCalendarImpl$DaysInMonth].
The following stack trace is thrown for debugging purposes as well
as to attempt to terminate the thread which caused the illegal
access.
This is a known issue with JAXB: JAXB was part of the JRE until version 11.
The default `j.x.bind.DatatypeConverter` implementation uses the thread
context classloader to find an implementation of
`j.x.datatype.DatatypeFactory` and binds it to a static field. Since
Xerces provides this service, the result is a nice memory leak.
To solve this, add:
javax.xml.datatype.DatatypeFactory =
com.sun.org.apache.xerces.internal.jaxp.datatype.DatatypeFactoryImpl
to your `catalina.properties` file.
