{code}
How to recreate?
{code:java}
public static void main( String[] args) throws ServiceException
{
ExecutorService executorService = Executors.newCachedThreadPool();
Service service = new Service();
service.setMaintainSession( true);
for (int i = 0; i < 50; i++)
{
executorService.submit( () -> {
Call call;
try
{
call = (Call) service.createCall();
call.setClientHandlers( new SomeClientRequestHandler(),
new AnotherClientResponseHandler());
}
catch (ServiceException e)
{
throw new RuntimeException( e);
}
}); }
}
{code}
Reason:
org.apache.axis.configuration.FileProvider.configureEngine(AxisEngine) uses
getInputStream() and setInputStream() methods to load the client config wsdd.
These getter and setter methods read or modify the 'myInputStream' class member
variable and is not thread-safe
Fix:
Use a local InputStream method local variable to load the client config file.
The stream is loaded and consumed in this method, so a local variable is
appropriate here. Please find attached the unified diff file with the proposed
fix.
