Runtime.getRuntime().exec() issue

Question

I'm trying to run another programm from Java code:

String[] command = {"gdal_polygonize.py", "/home/user/myoldfiles/proceeded.tiff", "-mask", "/home/user/myoldfiles/biomass_02.08.14.tif", "-f", "'ESRI Shapefile'", "/home/user/myoldfiles/proceeded.shp", "DN"};
Process p = Runtime.getRuntime().exec(command);

I have no file proceeded.shp created in /home/user/myoldfiles/ The command output obtained with BufferedReader looks like:

Creating output /home/user/myoldfiles/proceeded.shp of format 'ESRI Shapefile'.

When I run next command in terminal(Ubuntu)

 gdal_polygonize.py '/home/user/myoldfiles/proceeded.tiff' -mask '/home/user/myoldfiles/biomass_02.08.14.tif' -f 'ESRI Shapefile' '/home/user/myoldfiles/proceeded.shp'

It prints

Creating output /home/user/myoldfiles/proceeded.shp of format ESRI Shapefile.
0...10...20...30...40...50...60...70...80...90...100 - done.

And successfully creates proceeded.shp file. What am I doing wrong in Java code?

Thanks everybody for the help! I found solution here . The problem was in single quotes in 'ESRI Shapefile', I just deleted them and all works fine now!
