JDK-4165411 - java.lang.System: Forbid the modification of read-only system properties
Description
I'm trying to write a test to expose a problem in javac on Windows.

The broken code in javac was something like:

  dirname + "/" + basename

This was changed to:

  new File(dirname, basename).getPath();

I'm then trying to verify the change by running a test program like this:

  java -Dfile.separator='!' TestProgram

However, the File constructor uses UnixFileSystem.normalize which ignores
the value of UnixFileSystem.slash.  Consequently, my test fails.
Comments
EVALUATION As far as java.io is concerned, file.separator is considered a read-only system property. RFE 4165411 requests that we identify all of these properties.
