Nature		: Compiler Crash
----------------------------------------

The compiler crash can be experienced when the /usr/jdk/packges/lib/ext does not have the necessary directory permissions.

The system root has a directory structure /usr/jdk/packages/lib/ext and with the following directory permissions say
jlab213:root% ls -l /usr/jdk/packages/lib
drwx--x--x   3 root     root         512 Mar 28 17:05 ext

jlab213:~/src/extloader% cat Test1.java
public class Test1 {
        public static void main(String []args) {
                System.out.println(System.getProperty("java.ext.dirs"));
        }
}

jlab213:~/src/extloader 84 % javac Test1.java
