The "cannot find file for class" message is disabled by
-findirect-dispatch.  That's why Bryce and I thought you hadn't used
-findirect-dispatch.

So, I don't understand how this can have happened.  It may be some
other bug, of course, but I can't duplicate your result.  Maybe the
gcj you tested had itself been miscompiled.

For what it's worth, with cuurent HEAD I get:

zorro:~ $ ~/install/bin/gcj -shared -O -findirect-dispatch StandardServer.class
org/apache/catalina/core/StandardServer.java: In class 'org.apache.catalina.core.StandardServer':
org/apache/catalina/core/StandardServer.java: In method 'org.apache.catalina.core.StandardServer.storeConfig()':
org/apache/catalina/core/StandardServer.java:0: internal compiler error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.

If you will please cut and paste the command you tried, I can then
attempt to duplicate it.

TVM,
Andrew.
