Hello,

for contributions to the context-menu the visibleWhen-filter in project-explorer behaves different than in package-explorer:

Items for JavaProjects filtered by '<adapt type="org.eclipse.jdt.core.IJavaProject" />' are shown in pacakge-explorer but not in project-explorer.

Here's a simple menu which you can use to see the different handling on simple- and java-projects in package-/project-explorer:
