Description

When a PropertyDescriptor is enabled to dynamically modify the classpath e.g.

static final PropertyDescriptor URLS = new PropertyDescriptor.Builder()
.name("URLs to Load")
.description("URLs to load onto the classpath")
.required(false)
.defaultValue("lib/bootstrap/commons-lang3-3.12.0.jar")
.dynamicallyModifiesClasspath(true)
.identifiesExternalResource(ResourceCardinality.MULTIPLE, ResourceType.URL, ResourceType.FILE, ResourceType.DIRECTORY)
.build();

If the property is not set with a current value (URL), the additional classpath URL will not be added to the classloader by using the property's default value.
