Update Apache Santuario (XML Signature) to version 2.1.4

Summary

The update of Apache Santuario library from version 2.1.3 to version 2.1.4 introduces a new system property.

Problem

Apache Santurio 2.1.4 uses a new DocumentBuilder cache whose pool size can be configured with system property org.apache.xml.security.parser.pool-size. We will need to define an equivalent system property in JDK.

Solution

A new system property com.sun.org.apache.xml.internal.security.parser.pool-size is introduced in JDK. The function is equivalent to the Apache Santuario system property described above with a different "package" name that matches the imported class structure. The default value is 20, which is also the same as the default value of the Apache Santuario system property.

It's a tradition for JDK to use a different system property name when importing new Apache Santuario releases. This ensures there is no name conflict if both libraries are used.

Specification

No Spec change.
