Message mapping depends on the mapping technology:

i. Message, Java & XSLT (under Imported Archives) mappings are executed at Java stack;

ii. ABAP & XSLT (in ABAP stack) mappings are executed at ABAP stack.

The Integration Engine that processes the message pipeline (which runs in ABAP stack) will either execute a JCo call (using RFC Dest AI_RUNTIME_JCOSERVER) to the Java Stack to execute the mapping or, in the 2nd case, execute the mapping ABAP function directly.

The pipeline steps can be seen in the transaction SXMB_ADM ->Display Pipeline Definition

Here you have a good overview:
