The package is accessible from more than one module problem under VSCode only

I have a project which builds fine under grdle as well as in the IntelliJ IDE run configuration.

But it gives a problem in the VSCode IDE:

The package javax.crypto is accessible from more than one module

The are no module-info.java file in the entire project.

The modules listed are:

~/Desktop/dev/projects/pid2 % java --list-modules                                                                                                                                                                                                          
java.*
jdk.*

The VSCode User setting for the JDK is:

"java.home": "/Users/stephane.eybert/.sdkman/candidates/java/current",

and it is the version:

~/Desktop/dev/projects/pid2 % /Users/stephane.eybert/.sdkman/candidates/java/current/bin/java -version                                                                                                                                                      (master)pid2
openjdk version "11.0.2" 2019-01-15
OpenJDK Runtime Environment 18.9 (build 11.0.2+9)
OpenJDK 64-Bit Server VM 18.9 (build 11.0.2+9, mixed mode)

I tried with changing the JDK so as to use the same one as IntelliJ is using, but the problem remained the same.

The IntelliJ JDK version is:

~/Desktop % /Applications/IntelliJ\ IDEA.app/Contents/jbr/Contents/Home/bin/java -version
openjdk version "11.0.4" 2019-07-16
OpenJDK Runtime Environment (build 11.0.4+10-b304.77)
OpenJDK 64-Bit Server VM (build 11.0.4+10-b304.77, mixed mode)

The VSCode version is:
