Java segmentation fault after OS X 10.4.5 update

Anyone else having this problem? I use the Java VM to run programs for work every day. A few days ago, I installed the OS X 10.4.5 update, and now Java crashes each time I try to start it:

Computer:~/ username$ java -version
Segmentation fault

This looks suspiciously like the problem seen here in 10.3.9 after the update was applied.

I've tried rebuilding the Java cache using:

java -Xdump

per the instructions from the 10.3.9 link above, but I still get a segmentation fault when running this. Strange thing is that this only occurs on Java 1.4.2 (which is the release I have to use).

I can run 1.5.0 and 1.3.1 just fine, from their respective directories:

Computer:/System/Library/Frameworks/JavaVM.framework/Versions/1.3/Commands username$ ./java -version
java version "1.3.1_16"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.1_16-root_1.3.1_050718-17:36)
Java HotSpot(TM) Client VM (build 1.3.1_09-82, mixed mode)

Computer:/System/Library/Frameworks/JavaVM.framework/Versions/1.5/Commands username$ ./java -version
java version "1.5.0_05"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_05-83)
Java HotSpot(TM) Client VM (build 1.5.0_05-48, mixed mode, sharing)

Java 1.4.2 just crashes:

Computer:/System/Library/Frameworks/JavaVM.framework/Versions/1.4/Commands username$ ./java -version
Segmentation fault
