After upgrading to Java 1.4.1 or 1.4.2 from 1.3.1, an application compiled with -server runs for 8-10 hours, and then crashes. The call stack from the core file shows that the server VM crashed in the middle of a compile:

 ./dbx /usr/java1.4.2_02/bin/java /data/oss/etc/bin/core
For information about new features see `help changes'
To remove this message, put `dbxenv suppress_startup_message 7.1' in your .dbxrc
