Hi @wangweij, to complement @martinuy's answer, the following commands can
trigger this error message in the different described contexts:
java -Djava.security.properties=file:///etc -XshowSettings:security:properties
-Djava.security.debug=properties 2>&1 | head -22
java -Djava.security.properties==/etc -XshowSettings:security:properties
-Djava.security.debug=properties 2>&1 | head -22
java -Djava.security.properties==<(echo include /etc)
-XshowSettings:security:properties
This is also exercised by the test case:
