Why is ByteBuffer crashing?

Question

hi, i have a program where i want to write to a bunch of bytes, in small groups, to a ByteBuffer
of a specific size. Once that ByteBuffer reaches 50K bytes I want to write that whole thing
to a file as a ZipEntry. I have allocated the ByteBuffer and I can write to it the first time, but
the second time I try to write it says I have an IndexOutofBounds Exception. This does not
make sense to me because the first time I write I have 898 bytes written, the same with the
second time, and 898 + 898 < 50K for sure! I have posted the code below. Can anyone
help me? thanks
//variables:
     ByteBuffer buffer;
         int bytesInBuffer;
               if(buffer == null){
                                //the program goes here first, and executes fine....
                    buffer = ByteBuffer.allocate(50000);
                    buffer.put(claim);
                    bytesInBuffer += sizeOfClaim;
                    return true;
               buffer.put(claim,bytesInBuffer,claim.length);  //it crashes here the 2nd time through, even though the capacity of buffer is 50000!
               bytesInBuffer += sizeOfClaim;
               return true;

                    buffer = ByteBuffer.allocate(50000);
                    buffer.put(claim);

After the first time through be sure to flip the buffer via
a call to ByteBuffer.flip()
