Resolution

This is an issue raised in This content is not included.JBEAP-19731

Root Cause

In the rollOver method, the getFile can return a null value due to some error, then the java.lang.NullPointerException happens:

 private void rollOver() {
        try {
            final File file = getFile();
             setFile(null);
            // next, rotate it
            suffixRotator.rotate(getErrorManager(), file.toPath(), nextSuffix);
            // start new file
            setFile(file);
        } catch (IOException e) {
            reportError("Unable to rotate log file", e, ErrorManager.OPEN_FAILURE);
        }
}
