This Bugzilla instance is a read-only archive of historic NetBeans bug reports. To report a bug in NetBeans please follow the project's instructions for reporting issues.
Javadoc states that users can use whatever version of HTML their browser supports. According to w3cschools, all major browsers (6) support the above tags, as well as <del> (see below). Netbeans marks <s> and <strike> as "Unknown HTML tag" and marks it with a warning, but in the Javadoc Documentation panel, as well as in hover-pop-ups, it renders as expected. I expect, that if tags render correctly everywhere inside NetBeans, that they at least be recognized as valid tags. Note: HTML5 specifies the <del> tag as a replacement, because <s> was deprecated and subsequently re-assigned, but that does not render at all in Netbeans (and that's probably not NetBeans' fault).
Can this bug request also be expanded to include the <kbd> and <samp> elements which are valid in both HTML 4.1 and HTML5 but are reported by the NetBeans 8.0 editor window as unknown tags?
Unknown HTML tag hints give the same warnings as doclint. Reassigning for further evaluation.
The <q> tag (valid HTML 4 and 5) is also unrecognized by Netbeans 8.
Why is it marked as a JDK problem? The report is mainly about wrong warnings for tags, which are supported, but incorrectly underlined by the java editor.

The following output comes from javac 1.8.0_40 Test.java:3: error: unknown tag: s * Hello <s>World!</s>. ^ Test.java:3: error: unknown tag: s * Hello <s>World!</s>. ^
Has it been reported to the JDK?
