Don Yao commented on AXIS2-1927:
--------------------------------
We've fixed the problem by creating a new instance of SimpleDateFormat every
time it's called, rather than a static variable.
Thanks,
Don

> URL: https://issues.apache.org/jira/browse/AXIS2-1927
> Project: Apache Axis 2.0 (Axis2)
> Issue Type: Bug
> Components: adb
> Affects Versions: 1.1
> Environment: Linux Servers, Tomcat5, Axis2 1.1, Java 5.
> Reporter: Don Yao
> Priority: Critical
>
> We ran 50 simutanous users against Axis2 Web Services Server and got the some
> exceptions. We examined SimpleTypeMapper.java code and discovered that
> getStringValue method is using the un-threadsafe SimpleDateFormat. So we put
> synchronized block around the call:
> synchronized (SimpleTypeMapper.class) {
> return zulu.format(((Calendar) obj).getTime());
> }
