FULL PRODUCT VERSION :
java version "1.8.0_121"
Java(TM) SE Runtime Environment (build 1.8.0_121-b13)
Java HotSpot(TM) Client VM (build 25.121-b13, mixed mode)

ADDITIONAL OS VERSION INFORMATION :
Microsoft Windows [Version 10.0.10586]

A DESCRIPTION OF THE PROBLEM :
Dear support team,

Regression in implementation class java.security.Signature - class java.security.Signature$Delegate

method verify(String)

Java 8 update 112 - works,
Java 8 update 121 - throws exception:
"java.security.SignatureException: Invalid encoding for signature"
suppressedExceptions Collections$UnmodifiableRandomAccessList<E> (id=105)



REGRESSION. Last worked in version 8u112

ADDITIONAL REGRESSION INFORMATION:
// loading certificate on local computer
InputStream in = new Base64InputStream(SecurityUtil.createFileInputStream(new File(whitelistDir, certificateName)));
            CertificateFactory cf = CertificateFactory.getInstance("X.509");
            Certificate certificate = cf.generateCertificate(in);

// initialization of Signature
            Signature signature = Signature.getInstance("SHA1withDSA");
            signature.initVerify(certificate);
            
            // the checksum is done against the decoded utf-16 data
            signature.update(parameterWhiteListBytes);
            retVal = signature.verify(checkSigBytes);

***
where, parameterWhiteList = new String(parameterWhiteListBytes, "UTF-16BE");


exception happens on "retVal = signature.verify(checkSigBytes);" line only in Java 8 update 121 (update 112 - works fine).
Looks like issue is related to "suppressedExceptions Collections$UnmodifiableRandomAccessList<E> (id=105) "


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
run provided code.
If required, we can provide certificate file, signature and original "parameterWhiteListBytes"

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
works on Java 8 update 121
ACTUAL -
regression on Java 8 update 121

ERROR MESSAGES/STACK TRACES THAT OCCUR :
"java.security.SignatureException: Invalid encoding for signature"
suppressedExceptions Collections$UnmodifiableRandomAccessList<E> (id=105)

REPRODUCIBILITY :
This bug can be reproduced always.
