Calling the Class.getInterfaces() method causes the VM to core dump if the interface
class file is missing. The following is an example. If you compile Sample.java and
remove EmptyInterface.class and run Sample the VM gets a bus error.



zaphod: sigbus, 134 > cat Sample.java
class Sample implements EmptyInterface {
    public static void main(String[] args)
    {
Sample sample = new Sample();
System.out.println(sample.getClass().getInterfaces());
    }
}
zaphod: sigbus, 135 > cat EmptyInterface.java
interface EmptyInterface {}
zaphod: sigbus, 136 > javac Sample.java
zaphod: sigbus, 137 > rm EmptyInterface.class
rm: remove EmptyInterface.class (y/n)? y
zaphod: sigbus, 138 > java Sample
