Description

Hang is in the java library call java/io/InputStreamReader.getEncoding

Looking at the Derby code, this call is used to get the default encoding as a String, however
the default encoding value is not required, the localization code can just use the constructors
that use default encoding. Will attach a 10.1 branch patch soon. See if this can work around
the hang in the java library.
