On Java8Shim class, better to catch Throwable instead of Error

[JuanMiguelBG-Ticarum]

We working with PrimeFaces v13.0.8, that has a dependency with owasp-java-html-sanitizer.

With the 0240325.1 version, it has two new dependencies:

• Java 8 Shim
• Java 10 Shim

We working with Weblogic 12.2 and JDK 8.

When the application starts and process the class org.owasp.shim.Java8Shim, loading the static initializer block (line 21), with code

_instance = Class.forName("org.owasp.shim.ForJava9AndLater").newInstance();

The classloader returns a java.lang.ClassNotFoundException intead a java.lang.Error (or subclasses).

java.lang.ClassNotFoundException: Class, org.owasp.shim.ForJava9AndLater, was compiled with an incompatible version of Java. Make sure that all the classes needed by the application have been compiled with a compatible java version.

The originally error it's a java.lang.UnsupportedClassVersionError but the servers filters it and returns the exception that isn't catched, resulting in an application deploy error.
