Does im4java current version 1.4.0 supports ImageMagick 7.1.0-3 ??

The older versions used convert, but it seems with 7.1 /usr/bin/convert is a link, and the actual command is magick, i personally think BOTH should work and we have backward compatibility for im4java with regards to versions of ImageMagick. but since the upgrade, i get the following exception:

i upgraded ImageMagick from 6.7.2.7-2.el6 to 7.0.1-3

What is the command that is being executed? V7 has a stricter syntax checker than v6. In addition, there are a small number of changes.

EDIT: I should add, there have been many other changes since 6.7.2.

the command "identify" is being executed
plus im4java-1.2.0.jar is being used, i am upgrading the jar to 1.4.0 now. But not sure if that will solve the problem
