[jdk11u-dev] RFR: 8217017: [TESTBUG] Tests fail to compile after JDK-8216265

[Jie Fu]

I'd like to backport this patch to jdk11u to fix the build failure of test/jdk/java/nio/channels/spi/SelectorProvider/inheritedChannel/InheritedChannelTest.java.

Patch can be applied cleanly and only test code is affected.
Thanks.
