Why JBoss CLI throws ERROR parsing ? keys to aesh. Check your inputrc ?

Issue

• When having .inputrc file in home directory with the following content:

# Control characters
"\C-?":   backward-delete-char

• Getting the following ERROR Stacktrace in starting jboss-cli.sh:

[user@user bin]$ ./jboss-cli.sh -c
java.lang.RuntimeException: ERROR parsing ? keys to aesh. Check your inputrc.
