Jdt LambdaExpressionAndMethodRefCleanUp - comment dropped when converted to expression

[cal101]

The input

this.hashFunc = key -> {
			//默认使用FNV1hash算法			
			return HashUtil.fnvHash(key.toString());			
		};

becomes

this.hashFunc = key -> HashUtil.fnvHash(key.toString());

@Fabrice-TIERCELIN I read your ticket about important/not important comments and that non important comments may be removed. I agree there are cases like that depending on the cleanup used. But I think comments like the comment above explain most probably something about the solution and since only syntax is removed IMO it should be kept.
