This is definitely a bug. Just by looking at it, you can guess that it should most likely be changed like this:
if (typeName == null)
kind = new NullType();
else
kind = new ClassName(typeName);
fixTypes1(scc, kind);
However, we shouldn't fix a bug without reproducible use cases. How to reproduce this scene is too difficult. I tried for a long time and couldn't construct this example.
Among the existing test cases, only test83StackmapWithArrayType can reproduce the scenario where cv.dimension is not equal to 0. But it is difficult to construct a situation where lowersSet is empty.
If you can provide an example of reproducing the bug, I believe it will be easy for us to submit a PR that can be incorporated.

这肯定是一个Bug。简单看一下就可以猜到大概率应该这样改:
但是,我们不应该在没有复现用例的情况下修复一个bug。如何复现这个场景太难了,我试了好久都不能构造出这个例子。
现有都测试用例中只有test83StackmapWithArrayType可以复现cv.dimension不等于0的场景。但是很难构造出lowersSet是空的情况。
如果你能提供复现bug的例子,我相信我们很容易提一个可以合入的PR。
