Illegal character in path at index 16 [duplicate]

There’s an illegal character at index 16. I’d say it doesn’t like the space in the path. You can percent encode special characters like spaces. Replace it with a %20 in this case.

The question I linked to above suggests using URLEncoder:

String thePath = "file://E:/Program Files/IBM/SDP/runtimes/base";
thePath = URLEncoder.encode(thePath, "UTF-8");
