IllegalStateException "Recursive update" in ConcurrentHashMap

[mdescher]

Sometimes our builds run into an IllegalArgumentException with the message "Recursive update" thrown by ConcurrentHashMap.

Relevant part of stack trace:

Caused by: java.lang.IllegalStateException: Recursive update
    at java.util.concurrent.ConcurrentHashMap.transfer (ConcurrentHashMap.java:2552)
    at java.util.concurrent.ConcurrentHashMap.addCount (ConcurrentHashMap.java:2354)
    at java.util.concurrent.ConcurrentHashMap.computeIfAbsent (ConcurrentHashMap.java:1776)
    at com.webcohesion.enunciate.modules.lombok.LombokDecoration.getLombokMethodDecorations (LombokDecoration.java:52)
[...]
    at com.webcohesion.enunciate.modules.lombok.LombokDecoration.lambda$getLombokMethodDecorations$1 (LombokDecoration.java:54)
    at java.util.concurrent.ConcurrentHashMap.computeIfAbsent (ConcurrentHashMap.java:1708)
    at com.webcohesion.enunciate.modules.lombok.LombokDecoration.getLombokMethodDecorations (LombokDecoration.java:52)

LombokDecoration#getLombokMethodDecorations calls ConcurrentHashMap#computeIfAbsent on the CACHE ConcurrentHashMap. The passed in function later again calls ConcurrentHashMap#computeIfAbsent on the same hash map. The Javadoc of ConcurrentHashMap#computeIfAbsent states: The mapping function must not modify this map during computation.
