A QueryBatcher with RawCombinedQueryDefinition created with help of a Handle, when run, produces NPE
The same RawCombinedQueryDefinition when run with a QueryManager, produces the desired result.
Sample code:
WriteBatcher wbatcher = dmManagerTmp.newWriteBatcher();
wbatcher.withBatchSize(2);
InputStreamHandle contentHandle1 = new InputStreamHandle();
contentHandle1.set(new FileInputStream(dataFileDir + filenames[0]));
InputStreamHandle contentHandle2 = new InputStreamHandle();
contentHandle2.set(new FileInputStream(dataFileDir + filenames[1]));
InputStreamHandle contentHandle3 = new InputStreamHandle();
contentHandle3.set(new FileInputStream(dataFileDir + filenames[2]));
InputStreamHandle contentHandle4 = new InputStreamHandle();
contentHandle4.set(new FileInputStream(dataFileDir + filenames[3]));
InputStreamHandle contentHandle5 = new InputStreamHandle();
contentHandle5.set(new FileInputStream(dataFileDir + filenames[4]));
wbatcher.add(filenames[0], contentHandle1);
wbatcher.add(filenames[1], contentHandle2);
wbatcher.add(filenames[2], contentHandle3);
wbatcher.add(filenames[3], contentHandle4);
wbatcher.add(filenames[4], contentHandle5);
wbatcher.flushAndWait();
// get the combined query
File file = new File(combQueryFileDir + combinedQueryFileName);
String combinedQuery = convertFileToString(file);
// create a handle for the search criteria
StringHandle rawHandle = new StringHandle(combinedQuery);
rawHandle.setFormat(Format.JSON);
// create a handle for the search criteria
//FileHandle rawHandle = (new FileHandle(file)).withFormat(Format.JSON);
// create a search definition based on the handle
RawCombinedQueryDefinition querydef = queryMgr.newRawCombinedQueryDefinition(rawHandle);
/*String wordQuery = "<cts:word-query xmlns:cts=\"http://marklogic.com/cts\">" +
"<cts:text>unfortunately</cts:text></cts:word-query>";
StringHandle handle = new StringHandle().with(wordQuery);
RawCtsQueryDefinition querydef = queryMgr.newRawCtsQueryDefinition(handle);*/
StringBuilder batchResults = new StringBuilder();
StringBuilder batchFailResults = new StringBuilder();
// Run a QueryBatcher on the new URIs.
QueryBatcher queryBatcher1 = dmManagerTmp.newQueryBatcher(querydef);
queryBatcher1.onUrisReady(batch -> {
for (String str : batch.getItems()) {
batchResults.append(str)
.append('|');
}
});
queryBatcher1.onQueryFailure(throwable -> {
System.out.println("Exceptions thrown from callback onQueryFailure");
batchFailResults.append(throwable.getMessage());
batchFailResults.append("Test has Exceptions");
});
dmManagerTmp.startJob(queryBatcher1);
boolean bJobFinished = queryBatcher1.awaitCompletion(3, TimeUnit.MINUTES);

Actual output: What did you observe? What errors did you see? Can you attach the logs? (Java logs, MarkLogic logs)
Listener QueryFailure StringBuilder variable has java.lang.NullPointerException
Expected output: What specifically did you expect to happen?
URI returned in StringBuilder should be constraint5.xml.
Alternatives: What else have you tried, actual/expected?
Used a simple word-query as QueryDefinition, the results returned are as expected.
