file name of the linkfile should be >= 8: String index out of range: 8

[shenwei356]

I found an interesting thing. When the file name of the linkfile is shorter than 8, it reports:

java -jar camiClient.jar -d 123.txt .
String index out of range: 8

After changing 123.txt to 1234.txt, no error was reported.

Java version

$ java -version
openjdk version "1.8.0_151"
OpenJDK Runtime Environment (build 1.8.0_151-b12)
OpenJDK 64-Bit Server VM (build 25.151-b12, mixed mode)

Another thing: it still reports errors after successfully downloading files.

I guess it tries to detect whether the given value is a URL or file, cause the length of https:// is 8.
