Is there a different usage rationale for abstract classes/interfaces in C++ and Java

Question

According to Herb Sutter one should prefer abstract interfaces (all pure virtual functions) to abstract classes in C++ to decouple the implementation as far as possible. While I personally find this rule very useful, I have recently joined a team with many Java programmers and in the Java code this guideline does not seem to exist. Functions and their implementations are very frequently located in abstract classes. So did I get Herb Sutter all wrong even for C++ or is there a general difference in the usage of abstract functions in C++ compared to Java. Are abstract classes with implementation code more sensible in Java than in C++ and if yes why ?
