[Simple-support] Ignoring unavailable annotations (JAXB on Android devices)

Hello,
>From my research, it seems that Simple is the best XML
serialization/deserialization framework available for Android. The API and
the framework "feels right". Thank you very much for your efforts, esp. on
getting it to work on Android. :-)
I have started experimenting with Simple features and one issue that I need
help with is related to classes annotated both with JAXB and Simple (server
side is a servlet implemented using JAX-RS via RestEasy framework, hence the
use of JAXB). The following code works fine by itself (i.e. on a desktop
machine, as an Eclipse Java project) but fails to run on Android:
Serializer serial = new Persister();
File f = new File("somefilename.xml");
ItemCollection itemCollection = serial.read(ItemCollection.class, f);
The exception stack is below. This is happening because JAXB annotations
used on the ItemCollection class are not available on Android devices.
Is it possible somehow to ignore these annotations while using Simple on an
Android device? Does it require code change or is a workaround possible?
Thanks in advance for your help.
