Have Nb Platform without Javadoc and add javadoc in NB Platform Manager - Help > Javadoc Index Search and References are not updated. Also causes issue #138543. Fix requires changes to behavior of org.netbeans.api.java.queries.JavadocForBinaryQuery - it should allow JavadocForBinaryQueryImplementation#findJavadoc to return empty result instead of null (now it would break further search) and propagate changes in these empty results. Once this is fixed, change in issue #138543 should be reverted.
I guess the fix in issue #138543 would be to add nbm.needsrestart=true? If so, this is probably a P4. AFAIK the problem appears only if you had the project open _first_, then installed the module. If you install the module and then open the project you do not seem to need a restart.
Yes, API Documentation module will require restart, which is kind of odd, but you're probably right, this is rather P4 since other use cases are rare. I tried opening and creating projects and javadoc didn't show up. Maybe other actions or in different order trigger javadoc index refresh.
Not into 7.0 or next release. Feel free to reopen if more important than it seems.
