java.security.AccessControlException when using com.aspose.pdf.Document

Hi,

we have a command line tool which generates a .doc file using aspose.Words, and if some parameter is set, it converts it to PDF to place signature fields.

The tool operates under a security policy which denies access to everything except some internal folders, and to try to prevent problems with the PDF Document class looking for fonts, right before instantiating it, the code is:

List<String> paths = new ArrayList<>(1);
paths.add(Util.getFontsFolder());
com.aspose.pdf.Document.setLocalFontPaths(paths);

ByteArrayOutputStream baos = new ByteArrayOutputStream();
doc.save(baos, SaveFormat.PDF);
com.aspose.pdf.Document pdf = new com.aspose.pdf.Document(new ByteArrayInputStream(baos.toByteArray()));

so, before creating the pdf instance, the list of available fonts paths is set to the only one which can be accessed based on the security policy, and which I am certain contains the fonts needed, however we still get exceptions like:

        ... 6 more

If I add that path to the policy, it goes again in error with another different path, as if it is still trying some default fonts paths.

How do I set it so that it only checks in that single given folder?

Upon further inspection of the code, the issue is caused by the fact that class com.aspose.pdf.Document has a private static ThreadLocal<List<String>> variable, which is initialized with an empty new ThreadLocal().

When the method getLocalFontPaths is called, it checks the list in the thread local variable, and upon finding it null, it tries to initialize it with the default font paths, which is exactly what I do NOT want it to do.

By looking at the code, there seem to be no option to fix this behaviour at “call place”, so I think it must be fixed directly in your code.

@mtassinari,

The getLocalFontPaths method returns a list of local font directories and the default directory is already added. You can add and remove directories from this list, and then reset by calling setLocalFontPaths method. If this does not help, then kindly send all details of the scenario, including source PDF, font files and let us know which version of Aspose.PDF for Java API you are using. We will investigate and share our findings with you.

It should not be null and maintain a single custom directory path.

I cannot provide any source PDF nor fonts file because those would be completely irrelevant for the issue I am describing.

Here follows the decompiled code of class com.aspose.pdf.Document version 17.10:

As you can see, the private static ThreadLocal<List<String>> is initialized with a new ThreadLocal(), which at initialization time does not contain a List<String>.

If we follow the code path of a call to setLocalFontPaths:

  1. it calls on addLocalFontPath(String path)
  2. which in turn calls m1(String var0) (I guess that method has another name on the original source)
  3. which then calls getLocalFontPaths()
  4. which calls m22(), a method which tries to get the List<String> from the ThreadLocal
  5. since the ThreadLocal does not contain the list, it calls m2(boolean var0) passing false to initialize it
  6. which tries to load the default font paths by going back to m1(String var0) for each one
  7. and this causes the AccessControlException, because each of those paths is tested by creating a File instance and checking that exists and isDirectory, but the security policy we are using does not allow those paths to be accessed

In my opinion, this is an issue that must be solved by your dev team, and could be solved simply by adding a try { ... } catch { ... } around the code which instantiate the File to verify it exists, if an exception occur just consider as if the test was false.

@mtassinari

Thanks for sharing the requested details.

We are looking into the scenario and will get back to you with our findings soon. Please be patient.

@mtassinari,

Please download and try the latest version 18.1 of Aspose.Pdf for Java API. It does not initialize the object of type ThreadLocal at start (private static object). The old version 17.10 may have a bug. This is the decompiled code of class com.aspose.pdf.Document version 18.1: DecompiledDocument.zip (6.1 KB)

I am sorry but what you attached is not the “decompiled” version of class com.aspose.pdf.Document, it is just the bytecode!

And I just tried version 18.1.0, it still has the same bug, here is the real decompiled code:
