Nothing I can do about this. NetBeans internally uses javac, and Ant uses it to compile; javac recognizes int as a keyword and compiles it.
Fixing this would at a minimum, require support from the Java module in the form of implementing issue 163794.
Probably the right way to fix it would be:
- Java Card RI ships its own patched javac so compilation will fail even when run by Ant
- Java Platform module enhanced to allow a platform to specify some unsupported keywords / language features
- Java source module enhanced to look for unsupported keywords / language features
- Javac enhanced to use list of unsupported keywords/language features
Reducing to P3 - the build process will fail if you are using ints in a classic project. There is no way to fix this from the Java Card side.
Fixed - jcproject now uses hard-coded annotation processor to mark such things as errors. Project can still be compiled, but packager prevents deployment. |
Create "classic library project" ClassicLibrary1, add this method to created class: public int getValue() { return 555; } Build project. Create "classic applet package", add ClassicLibrary1 project to dependencies using project properties or "libraries" entry in project window. Change "process" method of generated applet: public void process(APDU apdu) { classiclibrary1.ClassicLibrary1 x = new classiclibrary1.ClassicLibrary1(); ISOException.throwIt((short) x.getValue()); } Build project.
