Which version of XXL-JOB do you using?

2.4.0

Expected behavior

when I used to connect to mongodb to do some aggregations.

new Document("from", "OutkeyChats")
--
.append("localField", "id")
.append("foreignField", "id")
.append("as", "uidVariables")),
new Document("$unwind", "$uidVariables"),
new Document("$match",
new Document("$or", Arrays.asList(new Document("uidVariables.uid",
new Document("$ne",
new BsonNull())),
new Document("$expr",
new Document("$eq", Arrays.asList(new Document("$strLenCP", "$chatId"), 8L)))))),

Actual behavior

I must use “\$”, or you will get a no class found error.

Steps to reproduce the behavior
