Content in trailing section of signature xml

[johan-fm]

Digidoc4j fails to read a signature when the signature file has trailing information after the xml tags. DigiDoc3 client opens the container correctly and displays the signature. This invalid_signature.txt is the ending of the signature file in question. If the comment is correct for the file then it seems to be created by "libdigidoc Android".

The error produced from parsing is:

org.digidoc4j.impl.bdoc.xades.XadesValidationDssFacade - Failed to parse xades signature: org.xml.sax.SAXParseException; lineNumber: 210; columnNumber: 24; Content is not allowed in trailing section.

Still getting this error with version 2.1.0
Failed to parse xades signature: org.xml.sax.SAXParseException; lineNumber: 205; columnNumber: 24; Content is not allowed in trailing section. [Fatal Error] :205:24: Content is not allowed in trailing section. Exception in thread "main" Invalid signature document

With .bdoc file that has two signatures and one of them has content in trailing section

[markoleek]

The error is still present in 3.3.0 and 4.0.0-RC1.

Could you provide us the test file you see the problem with? With the file we are using all seems to be okay.

Unfortunately I cannot, as I do not own the contents of the file and did not get permission to share it. You can contact me via email for further information.
