[BUG]: MakeWritable doesn't work for mac

Question

I'm trying to use oracle.jdeveloper.refactoring.util.MakeWritableHelper in my plugin, and I found it doesn't work for MAC. The byte code shows it only check the osname for "Windows" and "Linux".
and some Jdeveloper refactoring feature failed due to can't make file writable, they may also related to this class.

Answer 1

My MAC version is OSX 10.5.4.
I don't have a stacktrace. It just fails silently.
You can easily reproduce this bug by reformat a readonly file.
Here is the code I reverse engineered from oracle.jdeveloper.refactoring.util.Util.java:
public static boolean setReadOnly(java.net.URL url, boolean readOnly)
boolean ret = false;
java.lang.String cmdarray[] = null;
java.lang.String platformPathName = oracle.ide.net.URLFileSystem.getPlatformPathName(url);
java.lang.String osName = java.lang.System.getProperty("os.name", "");
if(osName.startsWith("Windows"))
cmdarray = (new java.lang.String[] {
"ATTRIB", readOnly ? "+R" : "-R", (new StringBuilder()).append('"').append(platformPathName).append('"').toString()
else
if(platformPathName.equalsIgnoreCase("Linux"))
cmdarray = (new java.lang.String[] {
"chmod", readOnly ? "u-w" : "u+w", (new StringBuilder()).append('"').append(platformPathName).append('"').toString()
if(cmdarray != null)
java.lang.Runtime runtime = java.lang.Runtime.getRuntime();
try
java.lang.Process process = runtime.exec(cmdarray);
if(process.waitFor() == 0)
ret = (new File(platformPathName)).canWrite();
if(ret)
oracle.ide.model.Node node = oracle.ide.model.NodeFactory.find(url);
if(node instanceof oracle.ide.model.TextNode)
oracle.ide.model.TextNode textNode = (oracle.ide.model.TextNode)node;
textNode.isReadOnly();
catch(java.io.IOException e)
e.printStackTrace();
catch(java.lang.InterruptedException e)
e.printStackTrace();
return ret;
}
