I'm running FreeBSD 4.10 with jdk 1.4.2p6.
Summary: The native JDK should provide the same stack
trace error as the linux-sun-jdk when it suffers from
a lack of entropy while generating random numbers..
rather than simply locking with no output.
I had a number of apps that locked solid with no debug
output or stack trace. I ran these apps using the
linux-sun-jdk and recieved an error relating to
seeding random numbers (I can recreate and paste the
stack trace if needed). I then switched back to the
native jdk and seeded /dev/random with 'rndcontrol -s
10' . Now the native JDK gets past the lock-up.
P.S. My solution to this is to set rndcontrol in a
startup script -- let me know if there is a better
