Looking at https://sourceforge.net/p/mobac/code/commit_browser
it seems that upstream has made a few Java9-related changes.

For example, https://sourceforge.net/p/mobac/code/2365/ must be related to

There is also an issue with proguard:

Source: mobile-atlas-creator
Version: 1.9.16+dfsg1
Severity: normal
User: debian-j...@lists.debian.org
Usertags: default-java9

This package fails to build with default-jdk pointing to openjdk-9-jdk.

The awful changes to generics in a couple of Swing classes seem to be
at fault. This probably requires pretty significant code changes to fix.
I recommend taking it up with upstream. See the Swing section on this wiki
