jrtfs is compiled twice, the second is to --release 8 so it can be packaged into jrt-fs.jar for use by IDEs/tools running on older JDK releases. So need to be careful with the changes here as it will likely causing build breakage.

We try to keep the changes to ASM to a minimum, might be better to leave this change out of the patch.

One or two of the sources changes should probably uses Files.copy, e.g. ZipPath, sjavac/CopyFile.java.
