[xmlvm-users] constant_pool.m and negative numbers

[Panayotis K. <pan...@pa...>]

Hello all!

When I had a peek at the file constant_pool.m (whereI believe is the pool for all static Strings), I found some entries with negative values.
Since the Java char datatype is an unsigned short, I have the feeling that these numbers are not right.

please send a small, self-contained example.

The iFireworks project.
There are 13 entries like this.
For a quick list:
cat .../constant_pool.m  | grep JAVA_ARRAY_CHAR | grep -

I was also trying to add a simple unicode string in the beginning of this demo.
Namely at the very beginning after applicationDidFinishLaunching, I added this code:
        System.out.println("QQQQ-Καλημέρα!");
I checked it and this does not contain any negative values.
When run, Xcode fails to attach to the executable and the binary crashes.

ah, ok. Now I understand. That should be OK. The values will be cast to 
an unsigned short by the C compiler. Perhaps it would be better to emit 
an unsigned short for clarity, but the current version should still be 
correct.
