Specifically, in my case emitting a class through ASM that has this in
it:
mv.visitMethodInsn(INVOKEDYNAMIC, "java/dyn/InvokeDynamic",
"dyn:getprop:helloText", "(Ljava/lang/Object;)Ljava/lang/String");
crashes the JVM sometime after it loads the class. Note how there's no
semicolon after "Ljava/lang/String"
