Caused by: java.lang.IllegalAccessError: class com.foo.Main (in module:

The exception message says: com.foo cannot read com.bar. Why?
Is not two situation equivalent? (before Implied readability and after)
This is bug?
I used the source from your mail to create a test case but I didn't
duplicate what you were seeing. In my test then I created two layers L1
and L2. In L1 then com.bar@1 and com.baz are mapped to the same loader
CL1. In L2 then com.bar@2 and com.foo are mapped to the same loader CL2.
The parent of L2 is L1. The parent of CL2 is CL1 with CL2 doing
local-first rather than parent delegation so that it loads the local
version of module com.bar's types.
The readability is setup as expected:
Module foo = layer2.findModule("com.foo").get();
Module bar2 = layer2.findModule("com.bar").get();
assertTrue(foo.canRead(bar2));
Module bar1 = layer1.findModule("com.bar").get();
assertFalse(foo.canRead(bar1))
I can't rule out a bug of course but I would need to see an outline of
what jakeplus.minicontainer.Bootstrapper is doing so that I can see how
the layers and class loaders are arranged.
