             Summary: XmlDomNodeImporterImpl should never rely on InputStream.available()
                 Key: SHRINKDESC-153
                 URL: https://issues.jboss.org/browse/SHRINKDESC-153
             Project: ShrinkWrap Descriptors
          Issue Type: Bug
          Components: spi
            Reporter: George Gastaldi


Some InputStream implementations return 0 in the available() method, however it is possible to read. This is described in the javadoc: 
{quote}
Returns an estimate of the number of bytes that can be read (or skipped over) from this input stream without blocking by the next invocation of a method for this input stream. The next invocation might 
 be the same thread or another thread. A single read or skip of this many bytes will not block, but may read or skip fewer bytes. 
Note that while some implementations of InputStream will return the total number of bytes in the stream, many will not. It is never correct to use the return value of this method to allocate a buffer 
 intended to hold all data in this stream.

The problematic code lies in
