Agreed. I'll expand [JDK-8179462](https://bugs.openjdk.org/browse/JDK-8179462) to remove `-XDignore.symbol.file` entirely, both as a javadoc and javac option and then add that issue to this PR.

Since that file cannot possibly compile without some additional modification to the JDK and/or JavaFX anyway, I don't see any harm removing this option from `build.gradle`. The right fix for the obsolete `sun.misc` usage in the `android` folder would be to replace `sun.misc.BASE64Encoder` with `java.util.Base64` as we did for the rest of JavaFX. I'll file a follow-on bug for that.
