Classloading with multiple parent layers JDK11 vs JDK14

[Alex Sviridov]

Hi all,
 
I have the following layers:
 
LayerA (moduleA)                   LayerB (moduleB)
             |_____________________|
                                 |
                   LayerC(moduleC)
 
LayerC has two parent layers layerA and LayerB and moduleC requires moduleA
and moduleB. When I start my application with JDK 11/14 I get no resolving errors
and everything is ok. However, when I use JDK 11 in moduleC when I use
application I get  java.lang.NoClassDefFoundError moduleB.Foo.class,
when I run with JDK 14 I don’t get such exception. The JDK I use listed
below.
 
Could anyone say — the behavior differs because of the different JDKs,
or the problem is that when multiple layers are parent there is possibility
that class won’t be found, or the problem is in my application?
