This is the regression introduced with fix for JDK-8013827. The code now checks if file exists before creating new temp file as oppose to earlier where an attempt was made to create file.

Code snippet:

File f;
        try {
            do {
                f = TempDirectory.generateFile(prefix, suffix, tmpdir);
            } while (f.exists());
            if (!f.createNewFile())
                throw new IOException("Unable to create temporary file");
        } catch (SecurityException se) {

The call to f.exists now needs "read" permission to be provided for applications which only need to write temp file.

Error:
java.security.AccessControlException: access denied
