Commit c10fc96a8ff98db4eb925a13ef0f5135ad8dacc6 - java-classpath-clojure

CLASSPATH-8: fallback to java.class.path on Java 9 Starting with Java 9, the default class loader is no longer an instance of URLClassLoader, so `classpath` returned an empty sequence. The strategy of using URLClassLoader started with release [0.2.0] to accommodate Java application containers (see [CLASSPATH-1] and [CLASSPATH-2]). After this change, application containers based on URLClassLoader should still work as expected. On Java 9 without an application container, it appears that the `java.class.path` system property is the only way to get the classpath. While this is essentially a bugfix for Java 9 compatibility, it is a change in behavior, hence the version change from 0.2 to 0.3. Stuart Sierra 6 years ago
