New candidate JEP: 411: Deprecate the Security Manager for Removal

[Geertjan Wielenga]

Also, from the point of view of Apache NetBeans, here’s a list of our
concerns with these developments:

https://blogs.apache.org/netbeans/entry/jep-411-deprecate-the-security

Apache NetBeans doesn't use java.lang.SecurityManager to guarantee
security, but rather to gain additional insight into the JVM's behavior.
Without having such insights, the IDE's user experience would be severely
affected.

Are replacement APIs being designed and will they be provided for
evaluation before JEP-411 is integrated?
Thanks,

Gj
