Thomas Fromm commented on ISPN-1514:
------------------------------------
Possible fix for AbstractMarshaller.objectFromInputStream:
public Object objectFromInputStream(InputStream inputStream) throws IOException,
ClassNotFoundException {
int len = inputStream.available();
ExposedByteArrayOutputStream bytes;
byte[] buf;
// ISPN-1514
if(len > 0){
bytes = new ExposedByteArrayOutputStream(len);
buf = new byte[Math.min(len, 1024)];
} else {
bytes = new ExposedByteArrayOutputStream();
buf = new byte[1024];
}
int bytesRead;
while ((bytesRead = inputStream.read(buf, 0, buf.length)) != -1) bytes.write(buf,
0, bytesRead);
return objectFromByteBuffer(bytes.getRawBuffer(), 0, bytes.size());
}

Solution:
In AbstractMarshaller.objectFromInputStream is assumed, that the available() method from
the incoming InputStream returns the size of data.
But this is optional, so the InputStream from the oracle driver returns 0. So
implementation of objectFromInputStream must be changed to avoid usage of available().
