There are tricky. I need to add test to cover them.
The problem comes from that this patch fails to

There are 3 nodes involving in the construction of a java.lang.String object.
1. Allocate of itself, aka. alloc
2. AllocateArray of a byte array, which is value:byte[], aka. aa
3. ArrayCopyNode which copys in the contents of value, aka. ac
Lemma
When a String object `alloc` is scalar replaced, C2
16 matches
