A general comment, the enum constructor situation is a bit tricky as 1) There is no 100% reliable way to determine which of a enum constructor's args are synthetic. 2) How a Java compiler generates enum constructors is a compiler-internal contract since all the enum constructors must be private. It is true that javac has consistently added two extra parameters as an implementation detail. Offhand, I don't know if ecj in particular has made the same choice. javac is not obliged to continue implementing enum constructors in this manner, so for better robustness, I think a fix in this space needs to be able to accommodate situations other than exactly N+2 parameters. ------------- PR: https://git.openjdk.java.net/jdk/pull/3082
