Found the bug in the code
https://github.com/apache/logging-log4j2/blob/master/log4j-api/src/main/java/org/apache/logging/log4j/message/StructuredDataId.java
{code}
public StructuredDataId(final String name, final String[] required, final
String[] optional,
final int maxLength) {
int index = -1;
if (name != null) {
if (maxLength > 0 && name.length() > MAX_LENGTH) {
throw new IllegalArgumentException(String.format("Length of id
%s exceeds maximum of %d characters",
name, maxLength));
}
index = name.indexOf(AT_SIGN);
}
{code}
