I created the smallest possible test set\n\nSo, I have two classes, in the first one I have a singleton (for the test the instance is not stored but it doesn't matter now) and, for some reason, I use a supplier to create the instance. This test works well if the supplier is created as an inner class or with lambda. It crashes when using the method reference (::new).\n\n``` java\npublic class Test1 {\n\n  Test1() {}\n\n  static Test1 get() {\n    Supplier\u003cTest1\u003e s = Test1::new;\n    return s.get();\n  }\n\n  interface Supplier\u003cE\u003e {\n    E get();\n  }\n}\n```\n\nSo there's a simple method get who creates the instance by using Test1::new method reference.\n\nThen there's a second class who calls the get():\n\n``` java\npublic class Test2 {\n  public static void main(String[] args) {\n    Test1.get();\n  }\n}\n```\n\nWhen compiled with retrolambda, bytecode 51, and executed, the output is\n\n\u003e Exception in thread \"main\" java.lang.VerifyError: Bad operand type when invoking \u003cinit\u003e\n\u003e Exception Details:\n\u003e   Location:\n\u003e     Test1.access$lambda$0(LTest1;)V @1: invokespecial\n\u003e   Reason:\n\u003e     Invalid type: 'Test1' (current frame, stack[0])\n\u003e   Current Frame:\n\u003e     bci: @1\n\u003e     flags: { }\n\u003e     locals: { 'Test1' }\n\u003e     stack: { 'Test1' }\n\u003e   Bytecode:\n\u003e     0x0000000: 2ab7 001f b1\n\u003e         at Test2.main(Test2.java:4)\n\nI tested with latest retrolambda 2.0.3 compiled with java 1.8.0_45\n","author":{"url":"https://github.com/pietrodev","@type":"Person","name":"pietrodev"},"datePublished":"2015-06-24T14:55:06.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":2},"url":"https://github.com/60/retrolambda/issues/60"}
