Description

For Java 8 it is enough to provide the path to the /usr/lib/jvm/openjdk-8/src.zip with the source files of the JDK with the Java Platform Manager/Sources. The I can click on a class like java.lang.String the source file for it is opened almost immediately.

For Java 11 providing the /usr/lib/jvm/openjdk-11/src.zip does not bring the source. There is no error message in the IDE log (View > IDE Log).

Unpacking the src.zip and then including each folder herein, from java.base to java.xml.crypto works - but it took minutes on my machine at high CPU load (Intel(R) Pentium(R) CPU B940 @ 2.00GHz, SSD drive).

Then I merged all sub-directories from the direcories java.base to java.xml.crypto together. The resulting structure is

com/
java/
javax/
jdk/
org/
sun/

(such as the structure before Java 9). Now I can open the Java sources for Java 11 as fast as before.

1. Could you please adapt the program such that I can provide a src.zip for the JDK and it opens the sources from where?
2. Could you please write an error in the IDE log when the source file was not found (including the absolute path of that file)?
