\texttt does not break in two lines

Question

I use \texttt to format some text. I need to break it into two lines if it exceeds the line width. I use \justify but it does not always work. The script below shows two examples one works well and the other does not. Can you identify why \justify does not work in one case?

\documentclass[sigconf]{acmart}
\newcommand*\justify{%
  \fontdimen2\font=0.4em% interword space
  \fontdimen3\font=0.2em% interword stretch
  \fontdimen4\font=0.1em% interword shrink
  \fontdimen7\font=0.1em% extra space
  \hyphenchar\font=`\-% allowing hyphenation
}
