Hello, I have searched everywhere (blackdown, dejanews, etc.) in vain for an answer to my jdb troubles. I am running RedHat 5.2 with the Blackdown JDK 1.1.7_v1a. When I try to run jdb if fails with an Internal Exception. Here is the debug info: root@bulldog:~# ping bulldog PING bulldog (127.0.0.1): 56 data bytes 64 bytes from 127.0.0.1: icmp_seq=0 ttl=64 time=0.1 ms --- bulldog ping statistics --- 1 packets transmitted, 1 packets received, 0% packet loss round-trip min/avg/max = 0.1/0.1/0.1 ms root@bulldog:~# ping localhost PING bulldog (127.0.0.1): 56 data bytes 64 bytes from 127.0.0.1: icmp_seq=0 ttl=64 time=0.1 ms --- bulldog ping statistics --- 1 packets transmitted, 1 packets received, 0% packet loss round-trip min/avg/max = 0.1/0.1/0.1 ms root@bulldog:~# root@bulldog:~/junk# cat hello.java public class hello { public static void main(String args[]) { System.out.println("hello"); } } root@bulldog:~/junk# javac -g hello.java root@bulldog:~/junk# jdb hello Initializing jdb...
