> BeanUtil Deserialize has exponential runtime error when deserializing arrays

>
> Key: AXIS2-3010
> URL: https://issues.apache.org/jira/browse/AXIS2-3010
> Project: Axis 2.0 (Axis2)
> Issue Type: Bug
> Components: adb
> Affects Versions: 1.2, 1.1.1
> Environment: Windows xp, tomcat, java 1.5, running POJO services via
> RPCServiceClient
> Reporter: Nathan Wray
>
> When an OMElement is deserialized into a POJO and the POJO has a
> setter/getter pair with an Array parameter, the result object is created and
> set into the POJO once for each member of the array. So for example an
> object with
> String [] getHeaders()
> void setHeaders(String[] h)
> where h[] is an array with 80 elements, the array h will be created 80 times
> and setHeaders will be called 80 times rather than once. This causes
> incredibly poor performance.
> It appears to be due to a pattern where each child in the element tree causes
> a jump back up to the parent and a re-creation of that array result. This is
> very easy to recreate by instrumenting a set method that accepts an array.
> I patched this locally in the 1_1_1 version of BeanUtil by changing line 283
> from
> PropertyDescriptor prty = (PropertyDescriptor)
> properties.get(partsLocalName);
> to
> PropertyDescriptor prty = (PropertyDescriptor)
> properties.remove(partsLocalName);
> This removes the definition of the set method after it's called the first
> time, so the remainder of the array elements don't cause the entire result to
> be recreated over and over.
> I looked at the 1.2 code and this does not appear to be resolved. The
> performance impact in my case, with 4700 result objects in an array, with
> each result object having a further array of 77 fields, was huge.
