Powermock / Javassist creates illegal constructors for JDK 1.7.0u65 and 1.8.0u11 with -target 7. ------------------------------------------------------------------------------------------------ Key: JASSIST-228 URL: https://issues.jboss.org/browse/JASSIST-228 Project: Javassist Issue Type: Bug Security Level: Public(Everyone can see) Affects Versions: 3.18.2-GA Environment: JDK 1.7.0u65 and 1.8.0u11 Reporter: Florian Burka Assignee: Shigeru Chiba Attachments: powermock-javassist-bug.tar.gz Javassist creates illegal constructors for JDK 1.7.0u65 and 1.8.0u11 with -target 7, I have a test that reproduces it at https://github.com/burka/powermock-javassist-bug . Somewhere in MainMockTransformer.transform(clazz), I think inside the PowerMockExpressionEditor, the responsible action must have taken place. If you remove -target 7 it works for both JDK 1.7.0u65 and 1.8.0u11. {code} Tests run: 1, Failures: 0, Errors: 1, Skipped: 0, Time elapsed: 0.003 sec <<< FAILURE! - in ConstructorTest testConstructorManipulationFailure(ConstructorTest) Time elapsed: 0.002 sec <<< ERROR! java.lang.VerifyError: Bad <init> method call from inside of a branch Exception Details: Location: MockedClass.<init>()V @32: invokespecial Reason: Error exists in the bytecode Bytecode: 0000000: 2a4c 120f b800 1503 bd00 0d12 16b8 001a 0000010: b800 204e 2db2 0024 a500 0e2a 01c0 0026 0000020: b700 29a7 0009 2bb7 002b 0157 b1 Stackmap Table: full_frame(@38,{UninitializedThis,UninitializedThis,Top,Object[#13]},{}) full_frame(@44,{Object[#2],Object[#2],Top,Object[#13]},{}) at java.lang.Class.getDeclaredConstructors0(Native Method) at java.lang.Class.privateGetDeclaredConstructors(Class.java:2658) at java.lang.Class.getDeclaredConstructors(Class.java:2007) at ConstructorTest.testConstructorManipulationFailure(ConstructorTest.java:13) {code} I created a powermock ticket at https://code.google.com/p/powermock/issues/detail?id=505
