javassist.Modifier was designed to be compatible to java.lang.reflect.Modifier.
So no isBridge() or isSynthetic().
javassist.bytecode.AccessFlag has BRIDGE and SYNTHETIC fields.
from javassist.
To do that, you have to check the existence of the Synthetic attribute.
from javassist.
Check MethodInfo#getAttribute(SyntheticAttribute.tag) != null
from javassist.
@chibash your strategy doesn't work for me... I am sure, I am working on a class with synthetic methods (java.lang.StringBuffer compiled with Java 8) - but the list of attributes retrieved via getAttribute() doesn't contain "Synthetic". Any idea? Were there related changes in the codebase?
from javassist.
getAttribute(SyntheticAttribute.tag) didn't work for me either. Checking the modifiers did work:
(method.getModifiers() & AccessFlag.SYNTHETIC) != 0
from javassist.
@kensei62 , you are right. I found in The Java® Virtual Machine Specification 4.7.8:
A class member that does not appear in the source code must be marked using a Synthetic attribute, or else it must have its ACC_SYNTHETIC flag set.
So both getAttribute(SyntheticAttribute.tag)
and (method.getModifiers() & AccessFlag.SYNTHETIC) != 0
must be checked.
