[MNG-6943] Activate profile depending of jdk version used in toolchain

**[Simon](https://issues.apache.org/jira/secure/ViewProfile.jspa?name=sbernard)** opened **[MNG-6943](https://issues.apache.org/jira/browse/MNG-6943?redirect=false)** and commented

I have one profile to configure `maven-javadoc-plugin` which is only activate for jdk 1.8 or greater. (doclint exist since java 1.8)
And another profile to use toolchain with jdk 1.7.

```xml

configure-doclint

[1.8,)




org.apache.maven.plugins
maven-javadoc-plugin

all,-missing

useToolchain



maven-toolchains-plugin



toolchain






1.7

```

The issue is that if I run  "`mvn install javadoc:javadoc -PuseToolchain" with java 8 or greater, t`his will failed with a "`Exit code: 1 - javadoc: error - invalid flag: -Xdoclint:none"`

I guess this is because **jdk version** which run maven is used instead of **toolchain jdk version**  to decide to activate or not "configure-doclint" profile.

Maybe it could make sense to add a new profile activation field \.
If no toolchain is used the current running version of maven should be used and so in this case behave like \

WDYT ?
