warning: [options] bootstrap class path not set in conjunction with -source 1.6

Newbie & Debugging Questions
#1

This has probably been asked a billion times before, but how do you get rid of that in your build console output?

#2

set bootstrap class path.

or use a newer JDK (the one javac uses).

or disable the warning with [icode]-Xlint:options[/icode] or similar.

#3

Think you mean use an older JDK! :wink:

AFAIK this warning was introduced with the javac in 1.7 to warn you that even though you’re specifying to compile as compatible with 1.6, if you compile against newer (1.7+) JDK classes your code may still not actually work on 1.6

Unless you’re specifically targeting 1.6 (in which case set its JDK as the bootstrap class path) then I assume you’re using an IDE where the project has the source level set. If you set that to the same as your JDK, this warning should disappear.

#4

ah ja, the other way around :slight_smile:
