I have a test failing that I'm running against Daffodil 2.7.0. I'm developing a large schema for a big obscure data format. I need the schema to work on Daffodil 2.7.0, so I'm hoping to find a workaround.
The bug does not occur in Daffodil 3.2.1. The issue seems related to the TDML runner's saving/reloading of the compiled schema. The test is a TDML parserTestCase with a data file, infoset, and expected validation errors. It is run validation="limited" and roundTrip="twoPass". Here's the error: Creating DFDL Test Suite for file:/home/mbeckerle/Documents/dataiti/git/dfdl-schemas/dfdl-p8/target/test-classes/com/owlcyberdefense/p8/p8-HfCommand.tdml java.lang.ClassCastException: cannot assign instance of scala.collection.immutable.List$SerializationProxy to field org.apache.daffodil.dsom.DPathCompileInfo.enclosingElementCompileInfos of type scala.collection.Seq in instance of org.apache.daffodil.dsom.DPathElementCompileInfo at java.base/java.io.ObjectStreamClass$FieldReflector.setObjFieldValues(ObjectStreamClass.java:2227) at java.base/java.io.ObjectStreamClass$FieldReflector.checkObjectFieldValueTypes(ObjectStreamClass.java:2191) at java.base/java.io.ObjectStreamClass.checkObjFieldValueTypes(ObjectStreamClass.java:1478) at java.base/java.io.ObjectInputStream$FieldValues.defaultCheckFieldValues(ObjectInputStream.java:2657) at java.base/java.io.ObjectInputStream.readSerialData(ObjectInputStream.java:2471) at java.base/java.io.ObjectInputStream.readOrdinaryObject(ObjectInputStream.java:2242) ....elided lots of serialized reading nested frames.... at java.base/java.io.ObjectInputStream.readObject0(ObjectInputStream.java:1742) at java.base/java.io.ObjectInputStream.readObject(ObjectInputStream.java:514) at java.base/java.io.ObjectInputStream.readObject(ObjectInputStream.java:472) at org.apache.daffodil.compiler.Compiler.reload(Compiler.scala:257) at org.apache.daffodil.tdml.processor.TDMLDFDLProcessorFactory.generateProcessor(DaffodilTDMLDFDLProcessor.scala:121) at org.apache.daffodil.tdml.processor.TDMLDFDLProcessorFactory.compileProcessor(DaffodilTDMLDFDLProcessor.scala:138) at org.apache.daffodil.tdml.processor.TDMLDFDLProcessorFactory.$anonfun$getProcessor$1(DaffodilTDMLDFDLProcessor.scala:154) at org.apache.daffodil.tdml.SchemaCache.doCompile$lzycompute$1(SchemaCache.scala:95) at org.apache.daffodil.tdml.SchemaCache.doCompile$1(SchemaCache.scala:95) at org.apache.daffodil.tdml.SchemaCache.$anonfun$compileAndCache$1(SchemaCache.scala:108) at scala.collection.mutable.HashMap.getOrElseUpdate(HashMap.scala:86) at org.apache.daffodil.tdml.SchemaCache$Cache.getOrElseUpdate(SchemaCache.scala:51) at org.apache.daffodil.tdml.SchemaCache.compileAndCache(SchemaCache.scala:107) at org.apache.daffodil.tdml.processor.TDMLDFDLProcessorFactory.getProcessor(DaffodilTDMLDFDLProcessor.scala:154) at org.apache.daffodil.tdml.TestCase.run(TDMLRunner.scala:756) at org.apache.daffodil.tdml.DFDLTestSuite.runOneTest(TDMLRunner.scala:390) at org.apache.daffodil.tdml.Runner.runOneTest(RunnerFactory.scala:144) at org.apache.daffodil.tdml.Runner.runOneTest(RunnerFactory.scala:150) at com.owlcyberdefense.p8.TestP8HfCommand.testHfCommand1Neg(TestP8HfCommand.scala:29) at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:77) at java.base/jdk.internal.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.base/java.lang.reflect.Method.invoke(Method.java:568) at org.junit.runners.model.FrameworkMethod$1.runReflectiveCall(FrameworkMethod.java:50) at org.junit.internal.runners.model.ReflectiveCallable.run(ReflectiveCallable.java:12) at org.junit.runners.model.FrameworkMethod.invokeExplosively(FrameworkMethod.java:47) at org.junit.internal.runners.statements.InvokeMethod.evaluate(InvokeMethod.java:17) at org.junit.runners.ParentRunner.runLeaf(ParentRunner.java:325) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:78) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:57) at org.junit.runners.ParentRunner$3.run(ParentRunner.java:290) at org.junit.runners.ParentRunner$1.schedule(ParentRunner.java:71) at org.junit.runners.ParentRunner.runChildren(ParentRunner.java:288) at org.junit.runners.ParentRunner.access$000(ParentRunner.java:58) at org.junit.runners.ParentRunner$2.evaluate(ParentRunner.java:268) at org.junit.internal.runners.statements.RunAfters.evaluate(RunAfters.java:27) at org.junit.runners.ParentRunner.run(ParentRunner.java:363) at org.junit.runner.JUnitCore.run(JUnitCore.java:137) at com.intellij.junit4.JUnit4IdeaTestRunner.startRunnerWithArgs(JUnit4IdeaTestRunner.java:69) at com.intellij.rt.junit.IdeaTestRunner$Repeater.startRunnerWithArgs(IdeaTestRunner.java:33) at com.intellij.rt.junit.JUnitStarter.prepareStreamsAndStart(JUnitStarter.java:235) at com.intellij.rt.junit.JUnitStarter.main(JUnitStarter.java:54) Process finished with exit code 255
