decodeBuffer have some problem

[hujiudeyang]

I want to write an output encrypted file
but wo have a question
decodeBuffer(InputStream aStream, OutputStream bStream) will Infinite loop.

public void decodeBuffer(InputStream aStream, OutputStream bStream) throws IOException {
        int totalBytes = 0;
        PushbackInputStream ps = new PushbackInputStream(aStream);
        this.decodeBufferPrefix(ps, bStream);

        while(true) {
            try {
                int length = this.decodeLinePrefix(ps, bStream);

                int i;
                for(i = 0; i + this.bytesPerAtom() < length; i += this.bytesPerAtom()) {
                    this.decodeAtom(ps, bStream, this.bytesPerAtom());
                    totalBytes += this.bytesPerAtom();
                }

                if(i + this.bytesPerAtom() == length) {
                    this.decodeAtom(ps, bStream, this.bytesPerAtom());
                    totalBytes += this.bytesPerAtom();
                } else {
                    this.decodeAtom(ps, bStream, length - i);
                    totalBytes += length - i;
                }

                this.decodeLineSuffix(ps, bStream);
            } catch (CEStreamExhausted var8) {
                this.decodeBufferSuffix(ps, bStream);
                return;
            }
        }
    }
