We tried to set "-Djava.library.path" for external library and we can find it seems there are 2 options to set the java options for it.

1.use JAVA_OPTS in setenv.sh
2.use LD_LIBRARY_PATH in setenv.sh

However, "-Djava.library.path" option can not be set through catalina.sh with a value "-Djava.library.path=$_NATIVE_LIBDIR" in case of 1st option.
Also, for 2nd option "-Djava.library.path" is set 2 times and the latter one is enabled, so this way is not valid.

As a result, we need to provide other way to add the custom "-Djava.library.path" through catalina.sh.
