  .
  Stack Trace: java.lang.IllegalArgumentException: Illegal Lookup
  object - originated from java.lang.invoke:
  java.lang.invoke.StringConcatFactory
          at
  java.lang.invoke.StringConcatFactory.<clinit>(StringConcatFactor
  y.java:193)

          at
  java.lang.invoke.MethodHandle.resolveInvokeDynamic(MethodHandle.
  java:660)
  .
  This occurs when any class in the java.lang.invoke package
  attempts to create a java.lang.MethodHandles$Lookup object for
  use in an invokedynamic instruction
  

Local fix

Problem summary

• The JVM was too restrictive in the access rights allowed to
  Lookup objects created for invokedynamic instructions from
  methods in the java.lang.invoke package.
  

Problem conclusion

• The JVM has been updated to allow invokedynamic instructions in
  the the java.lang.invoke package to have the same visibility as
  other bytecodes in the same classfile.
