Known bugs etc
While there are no known bugs in JHawk per se there are a couple of issues that may arise.
1. The introduction of the 'assert' keyword in Java 1.4
This version of JHawk will parse Java code written for versions of the Java compiler up to and including Java 1.8. Prior to Java 1.4 it was possible to use the word 'assert' in your code without any problem. As 'assert' is now a keyword code containing 'assert' in a position where it is deemed as being possibly a keyword e.g. variable, package, class or method names will not compile. JHawk will also detect this as a lexical error. It will continue processing other files but a message to the effect that 'assert' was detected in the code will appear in the system log.
2. The introduction of the 'enum' keyword in Java 1.5
This version of JHawk will parse Java code written for versions of the Java compiler up to and including Java 1.8. Prior to Java 1.5 it was possible to use the word 'enum' in your code without any problem. As 'enum' is now a keyword code containing 'enum' in a position where it is deemed as being possibly a keyword e.g. variable, package, class or method names will not compile. JHawk will also detect this as a lexical error. It will continue processing other files but a message to the effect that 'enum' was detected in the code will appear in the system log.
