Hi, there's some regression in java-1.7.0-openjdk-1.7.0.65 (probably this one [1]) that causes failure in our tests: Tests in error: initializationError(org.ovirt.engine.api.restapi.resource.BackendResourceInfoDetailTest): Bad <init> method call from inside of a branch Exception Details: Location: org/ovirt/engine/api/restapi/resource/AbstractBackendResourceLoggingTest.<init>(Lorg/powermock/core/IndicateReloadClass;)V @40: invokespecial Reason: Error exists in the bytecode Bytecode: 0000000: 2a2b 4e4d 1210 b800 1604 bd00 0d59 032d 0000010: 5312 a6b8 001b b800 213a 0519 05b2 0025 0000020: a500 0e2a 01c0 0027 b700 2aa7 000a 2c2d 0000030: b700 2a01 57b1 Stackmap Table: full_frame(@46,{UninitializedThis,Object[#39],UninitializedThis,Object[#39],Top,Object[#13]},{}) full_frame(@53,{Object[#2],Object[#39],Object[#2],Object[#39],Top,Object[#13]},{}) initializationError(org.ovirt.engine.api.restapi.resource.BackendResourceDebugDetailTest): Bad <init> method call from inside of a branch Exception Details: Location: org/ovirt/engine/api/restapi/resource/AbstractBackendResourceLoggingTest.<init>(Lorg/powermock/core/IndicateReloadClass;)V @40: invokespecial Reason: Error exists in the bytecode Bytecode: 0000000: 2a2b 4e4d 1210 b800 1604 bd00 0d59 032d 0000010: 5312 a6b8 001b b800 213a 0519 05b2 0025 0000020: a500 0e2a 01c0 0027 b700 2aa7 000a 2c2d 0000030: b700 2a01 57b1 Stackmap Table: full_frame(@46,{UninitializedThis,Object[#39],UninitializedThis,Object[#39],Top,Object[#13]},{}) full_frame(@53,{Object[#2],Object[#39],Object[#2],Object[#39],Top,Object[#13]},{}) If you spot this error, just downgrade to java-1.7.0-openjdk-1.7.0.60, which works fine.
