I found the thread I mentioned (Unexpected quit type 1 error).
Here's Apple's java link (use 2.2.5--2.2.6 is only for certain Oracle users)

If I can quote stief again but from the above thread:
"Seriously guys--time to start working with OS X if you want to keep participating in filesharing. I've watched LW struggle for almost two years to work with Apple's Java for Classic, but gnutella and java keep going foward, and java for Mac classic has remained stagnant. Troubleshooting LW and Classic just gets harder and harder, as our familiarity gets rustier and rustier.

Looks like the 4.1 series will be the last of LW for classic. The LW devs have held out for a long time (especially sberlin). . . and many of us have appreciated the efforts . . . but once you've tried OSX it's really hard to go back to any Internet activities on OS 9 and earlier.

[Aside: Sigh. I think I'll join an antique Macs club for nostalgia's sake before my wife throws out all my old Macs. Remember the thrill of Desk Accessories in Sys 6.0.7, was it?]"
