warning: [options] bootstrap class path not set in conjunction with -source 8 #21

Description

When following the eclipse setup instructions for the Processing Library Template, it mentions that "the full JDK is installed by default on Mac OS X" -- so the instructions do not recommend installing JDK in that case.

However, now that MacOS has moved on to JDK 10, both Eclipse and the ant build are generating warnings.

From the build log:

[javac] Compiling 2 source files to /Users/[...]/bin
[javac] warning: [options] bootstrap class path not set in conjunction with -source 8
[javac] 1 warning
[copy] Copying 1 file to /Users/[...]

This seems like a harmless warming (small test builds still work just fine) but:

It might make sense to have standard instructions in the README for everyone be to just install the correct JDK (8) and add it to the Eclipse project.

That would also avoid subtle errors -- especially ones that might become increasingly likely once MacOS JDK moves to 11+. It would also reduce the amount of red warning text in the logs!
