This is triggered by a (parallel) run of unit tests, and only extremely -infrequently. - -When it happens, it is because some way, somehow, Lang#describeConstable(TypeElement) is causing a DynamicConstantDesc -of NULL to be created for the module housing java.lang.String or java.lang.Object (!). (Obviously this should be a -DynamicConstantDesc representing java.base.) - -This *could* end up being a bug in the javac compiler. Or it can be a problem with the root set of modules.
