3383103 - Parameter cannot be added in As Java Config Tool - Exit code: [1]; output of the process - Error: Password * not found

While you are trying to add value to "com.sun.management.jmxremote.port" JVM parameter in Config Tool, error appears.

Configtool.trc shows the following entries:

[...]
com.sap.ASJ.cft.000065#BC-JAS-ADM-ADM-CFT#sap.com~tc~je~configtool#C0000A4D6115000000000001122D5CFA###configtool########Thread[AWT-EventQueue-0,6,main]#Plain##
JVM validation fails.
com.sap.engine.lib.config.api.exceptions.ClusterConfigurationException: Cannot validate jvm parameters - java process cannot start; Exit code: [1]; output of the process: [Error: Password * not found: /usr/sap/<SID>/<instnr>/exe/sapjvm_<X>/jre/lib/management/jmxremote.password]
[...]

Same issue can happen if you enable or disable this specific JVM parameter.
