Java extension causes apache application error

Hi, I'm running Apache 1.3.14 on WinNT 4 sp5. I've had PHP 4.0.3 previously installed and working fine. I just upgraded to PHP 4.0.4 and that also was working fine. Then I enabled extension=php_java.dll and setup my java variables in the PHP.INI file. Now whenever I attempt to process a php file I get an Application Error from Apache. If I attempt to process a php files that accesses Java class, the output is correct (the java classes are accessed), but I still get the application error. The error is about the instruction at such-n-such address referencing memory at 0x0000000. Any ideas. Gary
