Description

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:

    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();
        }
    }

Environment: Windows 7, Java 1.7.0_76-b13.

No problem on RHEL 1.7.0_75
