Fix CGPDFContextCreateWithURL JNI binding for macOS compilation

[Copilot]

The macOS native code for PDF support failed to compile due to incorrect JNI parameter marshalling in CGPDFContextCreateWithURL.

Changes

• OS.java: Changed mediaBox parameter annotation from flags=struct to cast=(const CGRect *) to match the macOS API signature
• os.c: Updated generated JNI code to pass pointer directly instead of dereferencing

Technical Detail

The JNI generator was dereferencing the CGRect pointer when the Core Graphics API expects a pointer:

// Before (compilation error)
rc = CGPDFContextCreateWithURL((CFURLRef)arg0, *lparg1, (CFDictionaryRef)arg2);

// After (matches API signature)
rc = CGPDFContextCreateWithURL((CFURLRef)arg0, (const CGRect *)lparg1, (CFDictionaryRef)arg2);

API signature: CGPDFContextCreateWithURL(CFURLRef url, const CGRect * __nullable mediaBox, CFDictionaryRef __nullable auxiliaryInfo)

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• ci.eclipse.org
  • Triggering command: /usr/bin/curl curl -s REDACTED (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

Original prompt

We have some problem with the mac part of the PDF support, so I tried to prepare your environment that it runs on a mac, can you check if that has worked? Then check the errors in https://ci.eclipse.org/releng/job/eclipse.platform.swt/job/PR-2882/1/consoleText and fix them.
