When we run the testcases in Eclipse or with maven we get the following error: java.lang.IllegalAccessError: Update to static final field com.company.common.rm.Cell.serialVersionUID attempted from a different method (ajc$preClinit1) than the initializer method <clinit> at com.company.common.rm.Cell.ajc$preClinit1(Cell.java:1) at com.company.common.rm.Cell.ajc$preClinit(Cell.java:1) at com.company.common.rm.Cell.<clinit>(Cell.java:1) at jdk.internal.reflect.GeneratedSerializationConstructorAccessor8.newInstance(Unknown Source) at java.base/java.lang.reflect.Constructor.newInstance(Constructor.java:490) at org.objenesis.instantiator.sun.SunReflectionFactoryInstantiator.newInstance(SunReflectionFactoryInstantiator.java:48) at org.objenesis.ObjenesisBase.newInstance(ObjenesisBase.java:73) at org.mockito.internal.creation.instance.ObjenesisInstantiator.newInstance(ObjenesisInstantiator.java:19) at org.mockito.internal.creation.bytebuddy.InlineByteBuddyMockMaker.createMock(InlineByteBuddyMockMaker.java:184) at org.mockito.internal.util.MockUtil.createMock(MockUtil.java:35) at org.mockito.internal.MockitoCore.mock(MockitoCore.java:63) at org.mockito.Mockito.mock(Mockito.java:1908) at org.mockito.Mockito.mock(Mockito.java:1817) at com.company.common.rm.RmPropsimTest.setUp(RmPropsimTest.java:85) It is strange since the Cell class does not see below. public abstract class Cell extends CellAdaptor implements WCell, LCell { protected Cell(String ldn, Provider provider, CellResource cellResource) { super(provider, ldn); } } I don't understand why it is complaining about serialVersionUID since class is not serialized or contains one. //mike
The component should be compile. I tried to reproduce it locally, reproduce it from one Enum. Orginal Enum: ``` public enum ExampleEnum { ENUM1, EMUM2; public static String getAnotherName(ExampleEnum arg) { return arg.name() + "_" + AspectUtil.getDeprecatedResult(); } } ``` After AspectJ compile: ``` public enum ExampleEnum { ENUM1, EMUM2; static { ajc$preClinit(); } private static final long serialVersionUID; public static String getAnotherName(ExampleEnum arg) { if (DeprecatedMethodsAspect.ajc$if$a6adfc1()) DeprecatedMethodsAspect.aspectOf().ajc$before$com_ericsson_commonlibrary_statisticscollectorframework_aspectj_DeprecatedMethodsAspect$1$b9499fc0(Factory.makeJP(ajc$tjp_0, null, null)); return String.valueOf(arg.name()) + "_" + AspectUtil.getDeprecatedResult(); } } ``` This strange serialVersionUID is generated. It only happens on Java11, can not generate on Java8.
The control for AspectJ to generate serialVersionUID is -XaddSerialVersionUID - you aren't setting that somewhere are you?
Andrew, you are right. serialVersionUID is generated -XaddSerialVersionUID. So I think it is runtime issue now. I did more comparisons, generated class with both compliance level 8 & 11, after decompile, find both have below: static { ajc$preClinit(); } private static final long serialVersionUID; But find runtime errors with compliance level 11. 1. Compliance level 8, run successfully on both JRE8 and JRE11. 2. Compliance level 11, met issue same as Mikael mentioned: can not update serialVersionUID during class initialization.
So the workaround is (unfortunately) don't set -XaddSerialVersionUID. The only real way to fix this I think is inline the serial version code into the actual clinit, but at the same time mark it some way so that the code doesn't become a candidate for join point shadows that might match a pointcut.
Checking the docs I see it says "Causes the compiler to calculate and add the SerialVersionUID field to any type implementing Serializable that is affected by an aspect. " - is it perhaps adding it to too many types I wonder? Worth me checking... Just looked and tested it and indeed it will only do it if they are Serializable, not any class.
