I had a problem reinstalling Java for OS X 2017-001 from  JavaForOSX.dmg downloaded today from

        https://support.apple.com/kb/DL1572?viewlocale=en_US&locale=en_US

I found a solution here that solved the problem.

I am repeating the info because the macrumors post had multiple questions and suggestions.

        1.  Download the JavaForOSX.dmg from https://support.apple.com/kb/DL1572?viewlocale=en_US&locale=en_US
        2.  Mount the dmg by double-clicking JavaForOSX.dmg
        3.  Open the Terminal ( /Applications/Utilities/Terminal ) and enter the following commands in sequence

                pkgutil --expand /Volumes/Java\ for\ macOS\ 2017-001/JavaForOSX.pkg ~/tmp
                sed -i '' 's/return false/return true/g' ~/tmp/Distribution
                pkgutil --flatten ~/tmp ~/Desktop/Java.pkg
                open ~/Desktop/Java.pkg
                (and proceed with installation)

        4.  Use AstroImageJ
