And the stack trace

ssexhd <- sighndlr <- call_user_handler <- qmkmgetConfig <- qmpxCfgGet
<- spefcpfa <- spefmccallstd <- peftrusted <- psdexsp <- rpiswu2 <- psdextp

Cause

shared_pool_size and java_pool_size were configured too small during the upgrade.

Solution

1. Restore a backup of the 10.2.0.4.0 database.
2. Set SHARED_POOL_SIZE = 250M and JAVA_POOL_SIZE = 250M.
3. Do the upgrade.

Note that rerunning catupgrd.sql after the error has already occurred will not help.  A restore of the pre-upgrade database has to be done.
