I could not find anything special about the dot character except that it is the 
reference operator in Java programming language statements.
Hence, the compiler accepts this in statements:

javax.
  imageio . stream	.
FileImageInputStream

So I guess, IcedTea-Web should accept white spaces around valid identifiers 
and/or the dot characters too, wherever it handles Java identifiers, package or 
fully qualified class names.
