Description
Not sure I've chosen the right repository to report the issue, but there's a similar one: #65
I can't see a "dataformats-text" explicit dependency so here's how I use it:
compile 'com.fasterxml.jackson.dataformat:jackson-dataformat-yaml:2.9.9'
compile 'com.fasterxml.jackson.core:jackson-databind:2.9.9.3'Below are tests proving it fails to parse numbers with underscores.
private static class LongHolder {
private Long v;
public Long getV() {
return v;
}
public void setV(Long v) {
this.v = v;
}
}
private static class IntHolder {
private Integer v;
public Integer getV() {
return v;
}
public void setV(Integer v) {
this.v = v;
}
}
@Test
public void testYamlUnderscores() throws IOException {
ObjectMapper mapper = new ObjectMapper(new YAMLFactory());
mapper.readValue("v: 1000000", IntHolder.class); // ok
mapper.readValue("v: 1_000_000", IntHolder.class); // ok
mapper.readValue("v: 1000000", LongHolder.class); // ok
// throws: com.fasterxml.jackson.databind.JsonMappingException: For input string: "1_000_000"
mapper.readValue("v: 1_000_000", LongHolder.class);
}
@Test
public void testJsonUnderscores() throws IOException {
ObjectMapper mapper = new ObjectMapper();
mapper.readValue("{\"v\": \"1000000\"}", IntHolder.class); // ok
// throws:
// com.fasterxml.jackson.databind.exc.InvalidFormatException: Cannot deserialize value of type `java
// .lang.Integer` from String "1_000_000": not a valid Integer value
// at [Source: (String)"{"v": "1_000_000"}"; line: 1, column: 7]
mapper.readValue("{\"v\": \"1_000_000\"}", IntHolder.class);
mapper.readValue("{\"v\": \"1000000\"}", LongHolder.class); // ok
// throws:

mapper.readValue("{\"v\": \"1_000_000\"}", LongHolder.class);
