SOLUTION : So you will have to do some further modification(s) on pkg installer file on your own with below instructions, ( Do not download/use someone else's modified pkg file, as it may have unwanted components in it ).

LEGACY JAVA FOR MAC INSTALL

PROBLEM : if you try to install Legacy-Java package/pkg/PKG in macOSX ( i think in macOSX Mojave or macOSX after it ) you will receive various ERRORS from macOSX installer 'This package is incompatible.', it will STOP INSTALLING, etc, As it is very old, etc. In macOSX Catalina (or in macOS-XI/11/X1 after it) download it in default ~/Downloads/ folder. So its easier+better that, for last binary+src of Legacy-Java 6 (1.6) (Java JRE+JDK 6 (1.6)) that is optimized for macOS, we should use Apple website: ( 'JavaForOSX.dmg' (en_US) file, 51.1MB, md5:5bc4ef2d2115f8b35bc6c0bd792477d5, sha1:10687ebc3d0965bd0fcbad600ae48ee84e0eff04.

And OpenJDK 6( 1.6), 7( 1.7), 8( 1.8) are available as Src-code form only, So dev/user have to compile Src-code to get macOS optimized binary for OpenJDK 6, 7 or 8. If App needs older than Legacy-Java 6 (1.6), then we have to get it from 'Oracle' site, as OpenJDK does not have older than Legacy-Java 6 (1.6).īy the way, OpenJDK's macOS optimized Java binary-files (and src-code) are available for Java 9 (1.9) & above, in OpenJDK archive-site. To obtain Legacy-Java, we can also get it from 'Oracle' website ('Oracle' purchased 'Sun', & 'Sun' developed Java), but Java from 'Oracle' is free only for Personal usage, & also needs user to free-registration in website, it is not-free for Commercial usage, & not-free if you want to distribute JRE with your App, etc.

OBTAIN JAVA : I suggest to use OpenJDK based Java (OpenJDK based Java release includes JDK & JRE) from site (it is free for any Commercial usage & also free for any Personal usage & you're free to include JRE/JDK with your App, etc ), use OpenJDK when a java-based App needs (latest) Java or Legacy-Java (not below Legacy-Java 6).

Then Apple macOSX stopped including any Java, so user had to load on their own. ( i think, upto Java SE 6 in upto macOSX High-Sierra 10.13 ).

One computer can have/use multiple versions of Java JRE/JDK, etc.

So user need to load those specific version, which is required by an App.

Some apps specifically need to use very specific (old) version of Java SE JRE/JDK, etc.

'LEGACY JAVA' is older version of Java SE JRE/JDK, etc. Run/double-click on 'JavaSE6.pkg' file inside ~/Downloads/tmp/ folder. Pkgutil -flatten ~/Downloads/tmp/OSXJavaSE6/ ~/Downloads/tmp/JavaSE6.pkg

Sed -i '' 's/return false/return true/g' ~/Downloads/tmp/OSXJavaSE6/Distribution

Hdiutil unmount '/Volumes/Java for macOS 2017-001/' Pkgutil -expand '/Volumes/Java for macOS 2017-001/JavaForOSX.pkg' ~/Downloads/tmp/OSXJavaSE6/
