Multiple threads can modify targetURL in HTTPSender
---------------------------------------------------
Key: AXIS-2540
URL: http://issues.apache.org/jira/browse/AXIS-2540
Project: Apache Axis
Issue Type: Bug
Components: Basic Architecture
Affects Versions: 1.4
Environment: all platforms
Reporter: Muruga Chinnananchi
Priority: Critical
Attachments: HTTPSender.java
the targetURL in HTTPSender is shared by multiple threads, in a highly
concurrent and multi-threaded environment, and multiple threads modifies the
targetURL and the messages endup going to wrong endpoint.
Our customers experienced this problem in production environment and we created
a simple test case to reproduce this, just place Thread.sleep(1000) right
before calling writeToSocket ( ) and try to send messages from multiple threads
to different endpoints. you would notice the messages going to wrong endpoints.
Fix: Remove the targetURL instance variable in HTTPSender.java and make it
local to the public void invoke(MessageContext msgContext) throws AxisFault
method. I am attaching the fixed HTTPSender.java. I fixed it on top of 1.4
release source. I thought it would benefit others who uses wsif-axis in
multi-threaded environment.
