NON-NLS tag ignored for specific method references targeting a string literal

[HannesWell]

In the following code the compiler issues a warning in the second line and does not consider NON-NLS tag.
Non-externalized string literal; it should be followed by //$NON-NLS-<n>$

List<String> list = List.<String>of();
list.removeIf("."::equals); //$NON-NLS-1$
list.removeIf(e -> ".".equals(e)); //$NON-NLS-1$
list.removeIf((Predicate<String>) "."::equals); //$NON-NLS-1$

In the third and fourth line no such warnings are emitted.

Please always supply full class that can be pasted (with class headers, method headers, imports etc) - the committers will thank you :)

I'll take a look.

Sure, no problem. Assumed you would prefer a minimal snippet, but can of course also make it complete.

I'll take a look.

Thanks.

A minimal snippet is minimal not only in terms of amount of code in it - but also minimal in how much work is needed in addition to reproduce the problem or write a junit test. So in that sense a complete but minimal snippet is best. Thanks.

I'll take a look.

Thanks.

See https://bugs.eclipse.org/bugs/show_bug.cgi?id=443456 - Unfortunately that considered only lambda expressions and the bug has stayed dormant in the case of reference expressions for some ten years !!!
