XYZ is sun proprietary api and may be removed in a future release

[Claude Moore]

I've been assigned the job to porting a large 1.6 Java desktop application to  java 8/11. Here and there, the code uses internal api, like, for example, sun.awt.causedfocusevent .
Is there any documentation about which public API replaced an internal API targeted to be removed ? I  know that not for each internal api that has been misused I'll able to find an equivalent public API, but at least I need
to know a point to start from.
Thanks in advance !

I thought it had to do with the package names: Oracle FAQ link.

Thanks Campbell for pointing that out. If I'm not wrong, there's no an 'official' replacement for any private, internal API classes (like the classes in sun.*  packages) , just because those are intended as 'implementation details' of a vendor-specific (Sun, Oracle) implementation, right ?
Ok, if that's the case, I'll need to make my own way to replace unsupported code with public api.
Hope to find someone's else solution over the web.

That's a pleasure

As far as I know, yes.

I just take it as given that any package with Sun's name is radioactive. Since Sun owned Java, it mostly only used its own package path for things that were experimental or not for public use.

There was one encoding class (I think) that was VERY popular in the Sun package path. Until they took it away entirely somewhere around Java 5 and it took YEARS to flush out all the stuff that got broken by that.

I think you mean sun.misc.BASE64Encoder. That still was available in Java 8 though (but as far as I could tell, not earlier).

Pretty sure that was the class, but the original package was under com.sun, not sun.misc.

At any rate, there's a non-sun implementation and has been for a long while. I migrated to that one.
