Implement java.io.File in vm/JavaAPI #4324
Conversation
…ion test. Implemented `java.io.File` using native methods in `vm/ByteCodeTranslator/src/nativeMethods.m` utilizing `NSFileManager` for iOS compatibility. Added comprehensive `FileClassIntegrationTest` which verifies the implementation by compiling Java source to C, linking with a POSIX-based native mock (for Linux CI compatibility), and executing the resulting binary. The test ensures correct Java-to-Native binding and basic file system operations.

- Added full implementation of `java.io.File` in `vm/JavaAPI` delegating to native methods. - Added native implementation in `vm/ByteCodeTranslator/src/java_io_File.m` supporting both iOS (`NSFileManager`) and Linux/POSIX. - Updated `ByteCodeTranslator` to package the new native source file. - Patched `vm/ByteCodeTranslator/src/nativeMethods.m` and `cn1_globals.m` to support compilation on Linux (added guards and stubs). - Added `vm/tests/src/test/java/com/codename1/tools/translator/FileClassIntegrationTest.java` to verify the implementation. - Fixed string concatenation issues in `vm/JavaAPI` exception constructors to resolve C compilation errors.

The new implementation of createNewFile() simply returns the boolean from createNewFileImpl and never throws, even though the signature declares throws IOException. The POSIX implementation returns false for any failure (e.g., parent directory missing or permission denied), so callers now get false instead of an exception and cannot distinguish “file already exists” from real I/O errors, diverging from the Java File contract.

The test uses a POSIX-based native implementation (native_test.c) to verify behavior on Linux CI environments where Foundation is unavailable, ensuring the Java logic correctly invokes native methods.Updated
