On Windows, when redirecting ProcessBuilder output to a file using ProcessBuilder.Redirect.appendTo(file), only file names up to 250 characters are allowed. Specifying longer filenames causes an IOException.

The IOException is misleadingly stating "Cannot find the file specified", e.g.:

Exception in thread "main" java.io.IOException: Cannot run program "hostname.exe": The system cannot find the path specified
        at java.lang.ProcessBuilder.start(ProcessBuilder.java:1051)
        at RedirectWithLongFilename.main(RedirectWithLongFilename.java:37)
Caused by: java.io.IOException: The system cannot find the path specified
        at java.lang.ProcessImpl.openForAtomicAppend(Native Method)
        at java.lang.ProcessImpl.newFileOutputStream(ProcessImpl.java:71)
        at java.lang.ProcessImpl.start(ProcessImpl.java:121)
        at java.lang.ProcessBuilder.start(ProcessBuilder.java:1030)
