Originally, I thought that this bug was another manifestation of 4249722
since the stack traces were similar. Well, 4249722 is fixed and this bug
still happens.

When HttpURLConnection.getResponseCode() is called on the client and
there is an HTTP continue response sent by a Win98 or WinNT server,
the VM will crash:

With HotSpot client on a S2.6 client, the following happens:

java_cmd=java
+ do_test thornback
+ java -version
java version "1.3beta"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3beta-M)
HotSpot Core VM (build 1.3beta-b-release, 1.3beta-b-release, interpreted mode, release build b)

Segmentation Fault

This bug is reproducible with a Win98 or a WinNT server. It is *not*
reproducible with a S2.6 server.

Yingxian determined that this VM crash was caused by extra CR characters
that were accidently included in the HTTP continue response header.
