FileSystemProvider

[Michael Hall]

Possibly related to https://bugs.openjdk.java.net/browse/JDK-8263940 <https://bugs.openjdk.java.net/browse/JDK-8263940>

I have recreated this with the JDK-16. I think it begins after JDK-12. I don’t have.a 13 it is present in 14.

javac -d . ~/Documents/GitHub/jdk16-master/test/jdk/java/nio/file/spi/TestProvider.java

Your test case. Not properly set up on git for me, but there.

The error is if -Djava.security.manager and -Djava.security.policy are used in invocation….

 /usr/libexec/java_home -v 14 --exec java -cp . -Djava.security.manager -Djava.security.policy=Classes/all.policy -Djava.nio.file.spi.DefaultFileSystemProvider=TestProvider Test

It loops until the StackOverflowError.
If not related should I do a bug report?
