Signing XML with SHA1 with DSA throws exception when key is larger than 1024.

[M. D.]

 Hello,

I'm getting the following exception when trying to sign an XML with a 2048 
bytes DSA key (sha1 digested).

Caused by: org.apache.xml.security.signature.XMLSignatureException: Invalid 
ASN.1 format of DSA signature
Original Exception was java.io.IOException: Invalid ASN.1 format of DSA 
signature

org.apache.xml.security.algorithms.implementations.SignatureDSA.engineSign(SignatureDSA.java:167)

org.apache.xml.security.algorithms.SignatureAlgorithm.sign(SignatureAlgorithm.java:139)
        at 
org.apache.xml.security.signature.XMLSignature.sign(XMLSignature.java:515)

I'm using the latest release 1.5.6 bundle.

Any help will be appreciated!

Best regards,
Marin
