Hello. Please review the fix for JDK 13. Bug: https://bugs.openjdk.java.net/browse/JDK-8222799 Fix: http://cr.openjdk.java.net/~serb/8222799/webrev.00
The "java.beans.Introspector" uses "declaredMethodCache" which was used before JDK-4058433: http://hg.openjdk.java.net/jdk/jdk/rev/ba387c302edd#l9.367 Note that "declaredMethodCache.put()" was removed, and now we never populate this cache. It is used only as a synchronization monitor in some methods. In the fix this cache was removed, and synchronization was moved to the ThreadGroupContext class. -- Best regards, Sergey.
