The core reflection used by the launcher can provoke linkage errors. Same thing happens in other usages when looking for constructors or methods.  That said, it does appear that this test creates a JAR file containing classes with dangling references. Changing the change to launch a helper class rather than launching SecurityManagerWarnings, and adding the helper to the JAR file, would avoid this.
