JNA fails to get resolved in Eclipse for Windows on Arm64 (WoA) #1465

Bundle-NativeCode: com/sun/jna/win32-aarch64/jnidispatch.dll; processor=aarch64; osname=win,
 ...<other values>...
The above attribute value is closest but not quite matching; the osname used in Eclipse is win32, not win, so this results in the JNA library (bundle) failing to be resolved by the OSGi container at runtime, and thus is considered 'missing' from its classpath.
Steps to reproduce
build a (custom) Eclipse SDK distribution for WoA, using the eclipse-platform repo, to get a zip package of the Eclipse SDK (amongst other SDKs artifacts)
unzip the package to a folder, and start up Eclipse SDK by invoking its eclipse.exe executable
the startup would fail with an error message and a pointer to the log file. The log file is big, so here's just some exceptions at the very top of the log file:

com.sun.jna is the bundle symbolic name (specified in MANIFEST.MF) of the jna-5.8.0.jar, and this bundle can't be resolved, as indicated in the above log messages.




    

If I modify the jna-5.8.0.jar's manifest and add the following value to its Bundle-NativeCode attribute:
com/sun/jna/win32-aarch64/jnidispatch.dll; processor=aarch64; osname=win32
then the Eclipse startup would work.
If needed, I can create a PR to add the above value to the build.xml of this repo (at line 491).
