WSDL generation breaks on multi-processor linux

           Summary: WSDL generation breaks on multi-processor linux
           Product: Axis
           Version: 1.0
          Platform: PC
               URL: http://localhost:8080/axis/Calculator.jws?wsdl
        OS/Version: Linux
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: WSDL processing
        AssignedTo: axis-dev@xml.apache.org
        ReportedBy: dwatson@msa.com


I have apache axis 1.0 deployed on Jetty 4.1.3 by copying the webapps/axis 
directory into the appropriate location, including xerces according to the 
documentation, and using the following xml to configure jetty:

<?xml version="1.0"  encoding="ISO-8859-1"?>
<!DOCTYPE Configure PUBLIC "-//Mort Bay Consulting//DTD Configure 
1.2//EN" "http://jetty.mortbay.org/configure_1_2.dtd">
<Configure class="org.mortbay.jetty.Server">
  <Call name="addListener">
    <Arg>
      <New class="org.mortbay.http.SocketListener">
        <Set name="Port"><SystemProperty name="jetty.port" 
default="8080"/></Set>
        <Set name="MinThreads">5</Set>
        <Set name="MaxThreads">100</Set>
        <Set name="MaxIdleTimeMs">30000</Set>
        <Set name="LowResourcePersistTimeMs">5000</Set>
      </New>
    </Arg>
  </Call>
  <Call name="addWebApplication">
    <Arg>/axis/*</Arg>
    <Arg><SystemProperty name="jetty.home" default="."/>/webapps/axis</Arg>
  </Call>
</Configure>

I then use the following command to start jetty:

java -jar start.jar etc/axis.xml

I am running the latest version of Redhat 8 on two different machines - a 
single processor Dell Optiplex GX1 and a dual processor poweredge 4300 server. 
I am using sun jdk 1.4.0_02. I can successfully deploy and load the 
Calculator.jws sample from the documentation on the single processor machine 
using the following url:

http://localhost:8080/axis/Calculator.jws?wsdl

However, if I make the same request on the dual processor machine, I get the 
following error:
