Puzzling warning message

[Thomas Hawtin]

I wonder if eventually class files will contain meta-info, e.g. needed
properties, version of JDK class is coded for, whether the enclosing
jar needs to be signed etc. so that you effectively manage you build
scripts with annotations.

You can tell what version of JRE is necessary by the version number in
the class file.

I'm not keen on looking up resources by hard coded literal strings. I;'m
in favour of generating statically safe code (whether Java 'source'
files or byte code) for such tasks.
