Tim Allison created COMPRESS-299:
------------------------------------

             Summary: Issue with a 7z encrypted file
                 Key: COMPRESS-299
                 URL: https://issues.apache.org/jira/browse/COMPRESS-299
             Project: Commons Compress
          Issue Type: Bug
            Reporter: Tim Allison
            Priority: Minor


A file that we are using to test SevenZ on Tika is failing in some environments.

I tested the soon to be attached file with commons compress trunk and received this exception:

This is the unit test: 
{noformat}
    public void testTikaEncryptedFile() throws Exception {
        String password = "Tika";
        SevenZFile sevenZFile = new SevenZFile(getFile("test7Z_protected_passTika.7z"), password.getBytes("UnicodeLittleUnmarked"));
        try {
            SevenZArchiveEntry entry = sevenZFile.getNextEntry();
            assertEquals("text.txt", entry.getName());

        } finally {
            sevenZFile.close();
        }
    }
{noformat}
