RFR: 8200610: Compiling fails with java.nio.file.ReadOnlyFileSystemException

[Archie L. Cobbs]

In `JavaCompiler`, when trying to write a class file, if an `IOException`s is thrown, instead of crashing, we report a normal error" `error while writing [file]: ...`.

However there are some I/O errors that can generate `RuntimeException`s not caught by this logic. So instead these errors cause a compiler crash.

An example is given in JDK-8200610, where the compiler tries to write into a ZIP file system and a `java.nio.file.ReadOnlyFileSystemException` is thrown.

This patch adds that exception and a couple of others which (in my estimation) could reasonably be expected to be thrown in various obscure cases involving alternative file systems: `FileSystemNotFoundException` and `InvalidPathException`.

Any suggestions on what the most appropriate list of exception types to include here are appreciated.
