[ovirt-devel] Strange error in CI when checking an engine patch

Hi, I'm getting a strange error from CI on one of my patches[1]. The error only happens in CI, local build passes OK. [ERROR] Tests run: 29, Failures: 0, Errors: 4, Skipped: 0, Time elapsed: 0.073 s <<< FAILURE! - in org.ovirt.engine.core.bll.quota.QuotaManagerTest [ERROR] testConsumeStorageQuotaSpecificOverThreshold Time elapsed: 0.022 s <<< ERROR! java.lang.VerifyError: Bad return type Exception Details: Location: org/mockito/internal/junit/ExceptionFactory$JUnitArgsAreDifferent.create(Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;)Ljava/lang/AssertionError; @10: areturn Reason: Type 'org/mockito/exceptions/verification/junit/ArgumentsAreDifferent' (current frame, stack[0]) is not assignable to 'java/lang/AssertionError' (from method signature) Current Frame: bci: @10 flags: { } locals: { 'java/lang/String', 'java/lang/String', 'java/lang/String' } stack: { 'org/mockito/exceptions/verification/junit/ArgumentsAreDifferent' } Bytecode: 0x0000000: bb00 0259 2a2b 2cb7 0003 b0 at org.ovirt.engine.core.bll.quota.QuotaManagerTest.assertAuditLogWritten(QuotaManagerTest.java:110) at org.ovirt.engine.core.bll.quota.QuotaManagerTest.testConsumeStorageQuotaSpecificOverThreshold(QuotaManagerTest.java:180) The whole log is here: https://jenkins.ovirt.org/job/ovirt-engine_master_check-patch-el7-x86_64/... The QuotaManagerTest class was changed in previous patches[2][3] in the topic branch, but for them the CI passes OK. Can someone point me to a possible cause?
