}
FileUtils.forceMkdirParent(outputFile);
final OutputStream fos = Files.newOutputStream(outputFile.toPath());
[...]
}
{code}
to:
{code:java}
protected void thresholdReached() throws IOException {
if (prefix != null) {
outputPath = Files.createTempFile(directory, prefix, suffix);
}
PathUtils.createParentDirectories(outputPath);
final OutputStream fos = Files.newOutputStream(outputPath);
