Calls within wrapper class with an abstract class falsely detected

[akwick]

CogniCrypt and Ruleset used: v2.7.1
Analyzed jar file: javautils-1.0_1.zip (Misuse is within Google Guava) | or simplified version wrapperMessageDigest.jar

Observed behavior: CogniCrypt reports a TypeStateError:

Unexpected call to method <java.security.MessageDigest: byte[] digest()> on object of type java.security.MessageDigest. 
Expect a call to one of the following methods 
java.security.MessageDigest: void update(byte[],int,int),
java.security.MessageDigest: void update(java.nio.ByteBuffer),
java.security.MessageDigest: byte[] digest(byte[]),
java.security.MessageDigest: void update(byte),
java.security.MessageDigest: void update(byte[])

Expected behavior: No misuse-report as the call happens in the method putLong.

When changing the code such that the wrapper class does not use an abstract class
wrapperMessageDigest_working.zip, no misuse is reported.
