Description

When unpacking an CPIO archive (made with the compress classes or even made with OSX cpio comandline tool) an EOF exception is thrown.
Here is the testcode:

final File input = getFile("cmdcreated.cpio");

final InputStream in = new FileInputStream(input);
CpioArchiveInputStream cin = new CpioArchiveInputStream(in);

CpioArchiveEntry entry = null;

while ((entry = (CpioArchiveEntry) cin.getNextCPIOEntry()) != null)

{ File target = new File(dir, entry.getName()); final OutputStream out = new FileOutputStream(target); IOUtils.copy(in, out); out.close(); }

cin.close();

Stacktrace is here:

java.io.EOFException
at org.apache.commons.compress.archivers.cpio.CpioArchiveInputStream.readFully(CpioArchiveInputStream.java:293)
at org.apache.commons.compress.archivers.cpio.CpioArchiveInputStream.getNextCPIOEntry(CpioArchiveInputStream.java:168)
at org.apache.commons.compress.archivers.cpio.CpioArchiveInputStreamTest.testCpioUnpack(CpioArchiveInputStreamTest.java:26)
...

This happens with the first read access to the archive. It occured while my try to improve the testcases.
