this issue happend only on starting AIX slave, which will try to find /com/sun/jna/aix-ppc64/libjnidispatch.so

However, in jna jar file, i don't found such file actually. the correct file should be com/sun/jna/aix-ppc64/libjnidispatch.a instead of *.so(which are for other unix/linux)

this issue will also cause the jobs always run fail on AIX slaves.
