Daniel Kulp commented on CXF-1917:
----------------------------------
Ummm... no it cannot be moved into AttachmentInInterceptor. The interceptors
are re-entrant. Thus, there could be multiple threads currently in the
AttachmentInInterceptor, all with their own message and thus, there would be
all kinds of issues if they all called ad.setMessage(...) at the same time.
I also don't know what the problem is. The Patter is a static. Thus, it's
compiled once and only once. They aren't compiled for every message.

> Key: CXF-1917
> URL: https://issues.apache.org/jira/browse/CXF-1917
> Project: CXF
> Issue Type: Improvement
> Components: Core
> Affects Versions: 2.0.7
> Environment: Windows XP, Java SE 1.6
> Reporter: Mayank Mishra
> Priority: Minor
> Attachments: AttachmentDeserializer.patch,
> AttachmentInInterceptor.patch
>
>
> AttachmentDeserializer contains static java.util.regex.Patterns which
> compiled for particular String expressions, which takes substantial time in
> milliseconds (around 50-100 ms).
> AttachmentDeserializer instance is created in AttachmentInInterceptor during
> handleMessage() call. This can be moved to AttachmentInInterceptor
> constructor, and provided a setMessage(Message message) method in
> AttachmentDerserializer, we can set message during handleMessage() call.
