NativeUtil crating tempfile throws exception

[DImuthuUpe]

Problem is with File temp = File.createTempFile(parts[0], "." + parts[1]); Where path[0] = /some directory path/filename. If path[0] = filename, this exception doesn't appear.

Can't we simply use File temp = File.createTempFile("temp", "." + parts[1]); ?

I'm not sure I understand what inputs are triggering this exception? What exactly is the problematic path?

[DImuthuUpe]

This gives exception
File temp = File.createTempFile("/META-INF/lib/tessbaseapi-macosx-x86_64", "." + parts[1]);

This works fine
File temp = File.createTempFile("tessbaseapi-macosx-x86_64", "." + parts[1]);

I guess problem is with creating temporary folders and this may be a JVM a specific issue.

[jahewson]

Ok, I see, it's expecting a filename but we've given a path. It would be nice to keep "tessbaseapi" somewhere in the temp file name, so instead of parts[0] I think we could use:

String prefix = new File(parts[0]).getName()
File temp = File.createTempFile(prefix, "." + parts[1]);
