09-05-2003
SUGGESTED FIX See the attached file, suggested-fix.sh. It applies a patch which fixes a hole in the checking for previously-unloaded classes, in ciEnv.cpp. The problem appears to be that references to types via field signatures do not check correctly for previously unloaded classes (check_get_unloaded_klass), because they probe the set of unloaded classes using the name variant "Lclassname;" rather than the unadorned classname. The other changes in the patch were useful for diagnosing this bug. The change in ciObjectFactory.cpp is an assertion that checks for the supposedly-impossible case of a class appearing loaded but then becoming unloaded. The other two changes cause the VM to hang on exit as long as both of the following two conditions are true: ShowMessageBoxOnError is true (defaults to false) is_error_reported() is true (only true after assertion or fatal) ###@###.### 2003-05-05
