I have the same problem....
You may circumvent this by doing the following:
SchemaCrawlerOptions = new SchemaCrawlerOptions();
schemaCrawlerOptions.setRoutineTypes(Arrays.asList(RoutineType.
procedure, RoutineType.unknown)); //RoutineType.function omitted: h2 do not
support fetching functions
Database database = SchemaCrawlerUtility.getDatabase(dataSource.
getConnection(), schemaCrawlerOptions);
You might have some use of the rest of my code too:
SchemaTextExecutable schemaTextExecutable = new SchemaTextExecutable
("schema");
schemaTextExecutable.getSchemaTextOptions().setHideConstraintNames(
true);
schemaTextExecutable.getSchemaTextOptions().setHideForeignKeyNames(
true);
schemaTextExecutable.getSchemaTextOptions().setHideIndexNames(true);
schemaTextExecutable.getSchemaTextOptions().setHidePrimaryKeyNames(
true);
schemaTextExecutable.getSchemaTextOptions().setHideTriggerNames(true
);
schemaTextExecutable.getSchemaTextOptions().
setHideRoutineSpecificNames(true);
schemaTextExecutable.getSchemaTextOptions().setShowUnqualifiedNames(
true);
schemaTextExecutable.getOutputOptions().setOutputFormatValue("json"
);
StringWriter stringWriter = new StringWriter();
schemaTextExecutable.getOutputOptions().setWriter(stringWriter);
schemaTextExecutable.executeOn(database, dataSource.getConnection
());
JSONArray report = (JSONArray) JSONValue.parse(stringWriter.
getBuffer().toString());
