Is jdb in 1.3.1 broaken? It's hanging when I try to use it. Maybe
I'm doing something wrong.
Here is my system information:
mobycarp% uname -a
FreeBSD mobycarp.org 4.4-STABLE FreeBSD 4.4-STABLE #0:
Thu Nov 8 12:22:24 CST 2001
wardd@mobycarp.org:/usr/src/sys/compile/MOBYCARP i386
Here is my java version info.
mobycarp% java -version
java version "1.3.1-internal"
Java(TM) 2 Runtime Environment, Standard Edition
(build 1.3.1-internal-wardd-011004-01:18)
Classic VM (build 1.3.1-internal-wardd-011004-01:18,
green threads, nojit)
Is there a way that I can confirm that this was compiled
with patch set 4? I'm almost certain that it is as I
downloaded the port in October.
Here is what I get when I start debugging. It hangs immediately after
I type run. The JVM is taking up %0 CPU usage.
