Strings read with `java.nio.files.Files.readString` may return incorrect strings when decoding with a charset other than US-ASCII, ISO08859-1, or UTF-8. Reading strings with other multi-byte charsets, such as UTF_16, may produce incorrect results.

As a work-around, disable compact strings by setting `-XX:-CompactStrings` on the command line.

This issue will be fixed in a future update.
