Missing huffman code table entry

[ErShakirAnsari]

I'm facing below exception when executed this command:

java -Xmx1024m -jar JPEGOptimizer.jar

I'm having the same issue with 2048m

I had the same problem. Seems to appear with some kinds of source files.
Added a fix in my pull-request:
if (iwParam instanceof JPEGImageWriteParam) { JPEGImageWriteParam jpegImageWriteParam = (JPEGImageWriteParam) iwParam; jpegImageWriteParam.setOptimizeHuffmanTables(true); }
The EXIF-data are not affected by that change, as far as I could verify.
