---------------------------------------------------------------
Adding constructors does not break BC since the old ones are still there to be
found. Breaking source compatibility is a pain but OK as long as we document
what users should do in Javadocs.
What does mvn clirr:check report. Also try japicmp.

> "Stream is not in the BZip2 format" exception on valid archive

> Key: COMPRESS-452
> URL: https://issues.apache.org/jira/browse/COMPRESS-452
> Project: Commons Compress
> Issue Type: Bug
> Components: Archivers, Compressors
> Affects Versions: 1.16.1
> Reporter: Tomisław Kityński
> Priority: Major
> Attachments: txt.7z
>
>
> The included 7z archive (with only one file), that is password protected, can
> be properly decompressed with 7z tool. Yet, getNextEntry() throws "Stream is
> not in the BZip2 format" exception.
> The code is:
> {code:java}
> private static final byte[] PASSWORD = "iBlm8NTigvru0Jr0".getBytes();
> public static void main(String[] args) throws IOException {
> String fileName = "r:/txt.7z";
> SevenZArchiveEntry entry;
> try (SevenZFile arch = new SevenZFile(new File(fileName), PASSWORD)) {
> while ((entry = arch.getNextEntry()) != null)
> { System.out.println(entry.getName()); }
> }
> {code}
> The same exception is thrown when one uses SevenZFile(SeekableByteChannel,
> byte[]) constructor. Password seems to be OK, since changing it yields
> different exception (and it also works in 7z tool).
> Full exception is:
> {noformat}
> Exception in thread "main" java.io.IOException: Stream is not in the BZip2
> format
