Description
Based on trying to resolve performance problems (for my use case, XStream badly lags JAXB 2.0), I found and resolved 3 hot spots that were easy enough to fix. One was for an existing issues (XSTR-506), but I didn't see entries for other 2.
Anyway, please see attached files for patched versions – I verified that they each resolved a hot spot (i.e. didn't show prominently in profiler output after change), and improved read (deserialize) performance significantly.

Hi Tatu,
thanks again for your patches. The patch for the SerializationMethodInvoker has been applied, the patch for the FieldAliasingMapper has been solved differently as such a Field class already existed in XStream's code base and the patch for the XmlFriendlyReplace has been applied and improved by adding a cache.
You may give the head revision a try ...

Jörg
