This is part of the weirdness of charsetmapping that Alan talks about. The charsetmapping data is shared between java.base and jdk.charsets in a way that makes it non-trivial to disentangle. 

So this reference to java.base is quite intentional -- replacing it with $(MODULE_SRC) would have pointed to src/jdk.charsets instead of src/java.base, which would have been incorrect.
