I am using the compiler version 1.1.
I compiled the Observer example as it is and it worked nicely.
Then I changed all the classes of the example just putting a package statement at the beginning of each one and put them all into a sub directory named the same of the package. The compiler reports the following errors.
Errors:
./src/xx\Observer.java:39,8:
Syntactic Error: unexpected token "invoke"
./src/xx\Observer.java:43,8:
Syntactic Error: unexpected token "invoke"
Does this problem still occur using the 1.2 beta5?
