Javadoc 1.4+ doesn't support the -1.1 switch anymore. Ignore this option.

Affected version

3.11.3

Bug description

Actual

I'm using the javadoc plugin in my project and always see this warning in the build:

[INFO] --- javadoc:3.11.3:jar (attach-javadocs) @ org.eclipse.equinox.p2.jarprocessor ---
[WARNING] Javadoc 1.4+ doesn't support the -1.1 switch anymore. Ignore this option.

but I can't find this in the options file or anywhere in the poms.
If I explicitly disable it with <old>false</old> I get the (expected) warning about deprecation, but javadoc-plugin still complains:

[INFO] --- javadoc:3.11.3:jar (attach-javadocs) @ org.eclipse.equinox.p2.jarprocessor ---
[WARNING]  Parameter 'old' (user property 'old') is deprecated: No reason given
[WARNING] Javadoc 1.4+ doesn't support the -1.1 switch anymore. Ignore this option.

How to reproduce:

1. checkout https://github.com/eclipse-equinox/p2
2. Go to bundles/org.eclipse.equinox.p2.core
3. run mvn verify -Pjavadoc

Expected

No warning is printed

• Remove Javadoc 1.4+ / -1.1 switch related warning #1240

Thanks for fixing that, I just wanted to ask the question as in

• [MJAVADOC-730] Deprecate parameter "old" #1101

the parameter was deprecated, and the old parameter is useless since Java 1.4 (end of public updates for Java 1.3 was March 2006 so round about 20 years ago) , maybe its time to simply completely remove that from the mojo.
