This archive contains unclosed entries.

Error message

This archive contains unclosed entries.

What it means

finish() refuses to finalize the archive while an entry is still open (putArchiveEntry was called without a matching closeArchiveEntry), because writing the end-of-archive records would produce a truncated, invalid tar. The caller must close the current entry first.

Solutions

1. Call closeArchiveEntry() for every putArchiveEntry() before finishing.
2. Use try/finally (or try-with-resources on the entry-writing logic) to guarantee closeArchiveEntry runs.
3. Write exactly currSize bytes so closeArchiveEntry itself succeeds before finish.

Example fix

// before
tar.putArchiveEntry(entry);
tar.write(data);
tar.finish(); // throws: unclosed entry
// after
tar.putArchiveEntry(entry);
try { tar.write(data); } finally { tar.closeArchiveEntry(); }
tar.finish();

// Ensure all entries are closed before finishing
if (openEntryCount > 0) { throw new IllegalStateException("close all entries before finish()"); }

try {
    tar.finish();
} catch (IOException e) {
    if (e.getMessage().contains("unclosed entries")) {
        tar.closeArchiveEntry(); tar.finish();
    } else throw e;
}

When it happens

Trigger: Calling finish() or close() after putArchiveEntry(entry) without calling closeArchiveEntry(); an exception in entry-writing code skipping closeArchiveEntry().

Common situations: Early returns/exceptions in the middle of writing an entry; forgetting closeArchiveEntry after copying entry data; conditional code paths that skip entry close.
