This is due to the missing "libmawt.so" in /soa/app/Oracle/product/fmw/Oracle_SOA1/soa/thirdparty/edifecs/XEngine/bin/headless

Solution:

Copy the libmawt.so library file from the JRockit installation directory (normally found in /lib/headless/) to the following directory:
%Middleware_HOME%/Oracle_SOA1/soa/thirdparty/edifecs/XEngine/bin/headless/
