Miroslav Pokorny commented on VFS-355:
--------------------------------------

replacing RamFileRandomAccessContent.InputStream.read(byte[],int,int) with the code below *WORKS*...

@Override
            public int read(byte b[], int off, int len) throws IOException {
                int count = -1;
                final int left = getLeftBytes();
                if (left > 0) {
                    count = Math.min(len, left);
                    RamFileRandomAccessContent.this.readFully(b, off, count);
                    ;
                }
                return count;
            }

> public int read(byte b[], int off, int len) throws IOException
> 			{
> 				int retLen = Math.min(len, getLeftBytes());
> 				RamFileRandomAccessContent.this.readFully(b, off, retLen);
> 				return retLen;
> 			}
> Notice retLen should return 1 if getLeftBytes() returns 0 but it doesnt. When empty it simply returns 0 which means if one reads until -1 it never happens...
