Up to 0.13.0 you could not mix up different separators in property names and lookup pathes. When setting "org.osjava.sj.delimiter=/" to be compatible with JNDI lookups e. g. under Tomcat property names as "a.b.c=123" had to be declared as "a/b/c=123". And when accessing existing property files with dot separated property names via Simple-JNDI lookups you had to lookup dot separated pathes too, what is quite unusual. Now there is support for dot separated property names combined with slash separated lookup pathes by setting jndi.syntax.separator to "/".
