Review Comment:
Hi @tkobayas , thanks for the PR.
IIUC:
1. the addMathContext() method has some kind of hidden side effect
2. the `invoke(operationType.getMethod("subtract", operationType,
MathContext.class));` need that side effect, to work.
3. this has to be replicated/duplicated for all the arithmetic operation
WOuld not be better to create a specific `invoke` methoed, to be called for
arithmetic operation, that
1. execute `mv.visitFieldInsn(GETSTATIC, "java/math/MathContext",
"DECIMAL128", "Ljava/math/MathContext;");`
2. execute ` invoke(operationType.getMethod("multiply", operationType,
MathContext.class));` (with name of operation received from parameter:)
e.g. (inside ClassGenerator)
```java
protected final void invokeArithmeticaOperation(Class<?>
operationType, String operation) throws NoSuchMethodException {
mv.visitFieldInsn(GETSTATIC, "java/math/MathContext",
"DECIMAL128", "Ljava/math/MathContext;");
invoke(operationType.getMethod("operation", operationType,
MathContext.class));
}
```
What do you think ? Does this make sense ?
