Loads library from classpath The file from classpath is copied into system temporary directory and then loaded. The temporary file is deleted after exiting. Method uses String as filename because the pathname is "abstract", not system-dependent.

Parameters:

path - The file path in classpath as an absolute path, e.g. /package/File.ext (could be inside jar)

Throws:

IOException - If temporary file creation or read/write operation fails

IllegalArgumentException - If source file (param path) does not exist

IllegalArgumentException - If the path is not absolute or if the filename is shorter than three characters (restriction of File.createTempFile(java.lang.String, java.lang.String)).
