By the way, considering the demangler is not an unimportant point as
any ambiguity in demangling is an ambiguity that can be happen when
linking C++ and Java code together. For example, your proposed
mangling for
java.lang.Math.acos(double)
appears to be
_ZN4java4lang4Math4acosEdd
which is the mangled name which will be used for the C++ function
java::lang::Math::acos(double, double)
