Assembler initialization - so it works when inside class initialization processes.
Assembler is an interface and constants are statics (implicitly or explicitly final)
which makes controlling order tricky.
Solution: initialization code (ie. inside jenaSystem.init) must use teh methods here,
and not Assembler.constant.
Use ConstAssembler.general(), not Assembler.general.
