Illformed appmaps get generated

There are circumstances where the events section of an appmap created by appmap-java is not created correctly.

For example, the appmap for org.elasticsearch.search.aggregations.bucket.terms.BytesKeyedBucketOrdsTests contains the sequences 74},,{" and $"},]}:

Alans-MacBook-Pro org.elasticsearch.search.aggregations$ tail -c+470630560 testExplicitCollectsFromSingleBucket.appmap.json | head -100
tic":false,"thread_id":74},,{"$ref":"$"},{"$ref":"$"},{"$ref":"$"},{"$ref":"$"},{"$ref":"$"},{"$ref":"$"},{"$ref":"$"},{"$ref":"$"},{"$ref":"$"},{"$ref":"$"},{"$ref":"$"},{"$ref":"$"},{"$ref":"$"},]}

The appmap for org.elasticsearch.search.aggregations.metrics.HyperLogLogPlusPlusTests.testMerge contains the sequence ":[,{":

Alans-MacBook-Pro org.elasticsearch.search.aggregations$ tail -c+$(expr 427988011 - 50) testMerge.appmap.json | head -c+200 | less
"lineno":72,"method_id":"readIntLE","parameters":[,{"defined_class":"org.elasticsearch.common.util.AbstractBigArray","event":"return","id":1159599,"lineno":81,"method_id":"size","path":"src/main/java/

The appmap for org.elasticsearch.search.aggregations.metrics.MedianAbsoluteDeviationAggregatorTests contains the sequence main/java,{"defined_class":":

Alans-MacBook-Pro org.elasticsearch.search.aggregations$ tail -c+$(expr 4692538 - 100) testSomeMatchesSortedNumericDocValues.appmap.json | head -c+150
"object_id":719878273,"value":"[Ljava.lang.String;@2ae87881"}],"path":"src/main/java,{"defined_class":"org.elasticsearch.common.settings.AbstractScope

It's possible that there were errors generated during the execution of these tests.

Beginne damit, die appmap-Generierung mit den aufgeführten Elasticsearch-Tests zu reproduzieren, einschließlich BytesKeyedBucketOrdsTests, HyperLogLogPlusPlusTests.testMerge und MedianAbsoluteDeviationAggregatorTests. Untersuche die Abschnitte der generierten Ereignisse rund um die gemeldeten Bytefolgen und vergleiche sie mit einer gültigen JSON-Struktur. Erledigt ist die Aufgabe, wenn diese Tests keine fehlerhaften appmap-Dateien mehr erzeugen.
