             Summary: Archive.toString might throw java.lang.IndexOutOfBoundsException
                 Key: SHRINKWRAP-407
                 URL: https://issues.jboss.org/browse/SHRINKWRAP-407
             Project: ShrinkWrap
          Issue Type: Bug
          Components: impl-base
    Affects Versions: 1.1.0-alpha-2
            Reporter: Tommy Tynjä
            Assignee: Tommy Tynjä


In some cases when outputting archive contents via the Archive.toString(Formatter) method, I get a java.lang.IndexOutOfBoundsException when writing to the output stream. After some investigation I found the cause being an erroneous calculation in the buffered write.

The error can be reproduced with the following test case added to ArchiveWriteToTestCase in impl-base:

{code:java} 
@Test
public void shouldBufferWritesCorrectly() throws IOException {
    MockOutputStream outputStream = new MockOutputStream();
    byte[] content = new byte[9202];
    for (int i = 0; i < content.length; i++) {
        content[i] = (i + "").getBytes()[0];
    }
    IOUtil.bufferedWriteWithFlush(outputStream, content);
    Assert.assertArrayEquals("Inconsistent writes?", content, outputStream.getContents());
}
{code}
