Environment

jruby 9.2.7.0 (2.5.3) 2019-04-09 8a269e3 OpenJDK 64-Bit Server VM 11+28 on 11+28 +jit
Windows 10

Expected Behavior

Should not receive warning about "Native subprocess control requires open access to sun.nio.ch" since this was supposed to have been addressed in #5642 which was included in 9.2.7

Actual Behavior

Even running simple tasks from the command line I get the following warnings:

$ jruby -version
