Comment # 3 on bug 239 from Simon Arlott

Created attachment 98 [details]
Patch to fix 2 of the 3 reported issues

1. SLF4J 1.7.x requires Java 1.5, so use StringBuilder

2. Create HashMap on demand in deeplyAppendParameter()
   with the default map size because the array size is
   not an indicator of how many map keys will be put
   without knowing how many elements are also object
   arrays

3. Not implemented as the Logger interface only accepts
   a format String, not a StringBuilder
