SignaturePolicyVerifier leaks stream upon exception

[GoogleCodeExporter]

What steps will reproduce the problem?
1. In SignaturePolicyVerifier.verify(), the code calls StreamUtils.readWrite() 
followed by a close within the same try-catch. This will skip the call to 
sigDocStream.close() if the readWrite() throws an exception. A better idiom is 
to call sigDocStream.close() in a finally clause. There are examples of this in 
xades4j.utils.Base64

What is the expected output? What do you see instead?
The stream obtained from 
policyDocumentProvider.getSignaturePolicyDocumentStream(policyId) should be 
closed even if reading the stream causes an IO exception.

What version of the product are you using? On what operating system?
1.2.0
Windows 7
