Auto (Organize) import works but not for all JDK classes

[mstup]

VSCode: Version: 1.85.2
OS: Linux x64 4.16.11-100.fc26.x86_64
Extensions:

• Extension Pack for Java v0.29.0

Auto import resolve Collection classes, probably some other, but can't resolve java.awt.Toolkit class to auto import.
Hotkey combination did nothing as well.

BTW: Used external predefined JAVA_HOME and JDK 11.0.9.fx-zulu

$> env | grep JAVA_HOME
JAVA_HOME=/home/mykola/.sdkman/candidates/java/current
$> java -version
openjdk version "11.0.9" 2020-10-20 LTS
OpenJDK Runtime Environment Zulu11.43+21-CA (build 11.0.9+11-LTS)
OpenJDK 64-Bit Server VM Zulu11.43+21-CA (build 11.0.9+11-LTS, mixed mode)

Example of simple project to reproduce issue vstest.zip

According to this comment, this is expected behavior. But not clear why ?!
The chance to develop Swing base Java application without chance to never import Java AWT classes is close on zero.
