ISPN cache is hung when try to read data from DB

Have a look on AbstractMarshaller.objectFromInputStream(InputStream inputStream).
When inputStream.available() returns 0 (but it doesn't mean that stream is empty) we have never ended cycle below

while ((bytesRead = inputStream.read(buf, 0, buf.length)) != -1) bytes.write(buf, 0, bytesRead);

I personally can reproduce this with Oracle DB
