Refactored using
find . -type f -name "*.java" |\
xargs sed -i -E |\
's/\.createStanzaCollectorAndSend\((\w+)\)\.nextResultOrThrow\(\);/.sendIqRequestAndWaitForResponse(\1);/'
and some manual refactoring.
This also resulted in a refactoring of the Providers and parsing
Exceptions. NumberFormatException and ParseException can now be thrown
directly, the wrapping in a SmackParsingException is down at a higher
layer, i.e. in AbstractProvider.
