To further clarify the report:

When the attached proof-of-concept is executed, a RuntimeException is raised, which has a comment "Should never happen".

The issue isn't due to SIGCHLD, but rather following a waitpid() call.  The code attempts to suss the exit code / reason for waitpid() returning, but does not check for WIFSTOPPED in its handler.
