When running jdeps on a relatively simple app like HelloWorld the output will look something like this (the formatting seems to get lost in Jira, but the point is that the lines are very long):

$ jdeps ~/HelloWorld.class
HelloWorld.class -> java.base
   <unnamed> -> java.io java.base
   <unnamed> -> java.lang java.base

In particular, even though the module and package names are relatively short, the lines jdeps output are in this case ~117 columns wide. If the terminal (window) has fewer columns than that the output will be very hard to read.

When possible jdeps should make the output more compact to better fit the terminal.
