Hi Claes, src/java.base/share/classes/java/lang/invoke/InvokerBytecodeGenerator.java
96 /** Internal name lookup cache. */ 97 private HashMap<Class<?>, String> nameMap; 617 nameMap = new HashMap<>(2); Have you tested it with IdentityHashMap? Maybe it would be even better as Class<?> does not have own implementations of #hasCode() and #equals() methods.
