ADDITIONAL SYSTEM INFORMATION :
Ran 'jdeps' on Windows 10, expecting the bug to be OS agnostic.

A DESCRIPTION OF THE PROBLEM :
The name of the generated .dot file using jdeps `--dot-output` option does not follow constant pattern as it is described in its documentation at: https://docs.oracle.com/javase/10/tools/jdeps.htm#JSWOR690 It states:
"...one '.dot' file for each analyzed archive named 'archive-file-name.dot'..."

This holds true for legacy jars, and for jars providing an 'Automatic-Module-Name'. The expected '.dot' file name changes when jdeps analyzes a modular jar, i.e. it contains a compile module descriptor.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Download 1: http://central.maven.org/maven2/org/ow2/asm/asm/5.2/asm-5.2.jar
Download 2: http://central.maven.org/maven2/org/ow2/asm/asm/6.2.1/asm-6.2.1.jar

Running 'jdeps --dot-output . asm-5.2.jar' produces 'asm-5.2.jar.dot'
Running 'jdeps --dot-output . asm-6.2.1.jar' produces 'org.objectweb.asm.dot'

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Running 'jdeps --dot-output . asm-6.2.1.jar' should also produce a file with a name based on the analyzed jar file : 'asm-6.2.1.jar.dot'
ACTUAL -
Running 'jdeps --dot-output . asm-6.2.1.jar' produces 'org.objectweb.asm.dot'

FREQUENCY : always
