Description

Checkstyle cannot parse an automatically initialize array in method call.

I experience the issue with both maven-checkstyle and eclipse-checksyle.

The following code causes checktyle:check to fail. The issues is cause by the second parameter.

final SanitisingBeanRecordFieldExtractor extractor =
                new SanitisingBeanRecordFieldExtractor(CreditCardRecord.class,
                        { "transactionDescriptionLineText" },
                        AbstractTransactionRecord.DATE_FORMAT, HASH_KEY);

The checksyle:check fails with the following error.

.../SanitisingBeanRecordFieldExtractorTest.java:109:15: expecting "class", found 'SanitisingBeanRecordFieldExtractor'
.../SanitisingBeanRecordFieldExtractorTest.java:110:78: expecting IDENT, found ','

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-checkstyle-plugin:2.17:check (default) on project sense-batch: Failed during checkstyle configuration: MismatchedTokenException occurred during the analysis of file .../SanitisingBeanRecordFieldExtractorTest.java. expecting EOF, found 'extractor' -> [Help 1]

To work around the code needs to be changed to the following:

final SanitisingBeanRecordFieldExtractor extractor =
                new SanitisingBeanRecordFieldExtractor(CreditCardRecord.class,
                        new String[] { "transactionDescriptionLineText" },
                        AbstractTransactionRecord.DATE_FORMAT, HASH_KEY);

For reference the constructor I am calling is defined as follows:

public SanitisingBeanRecordFieldExtractor(final Class<?> type, final String[] fields,
            final String dateFormatPattern, final String hashKey) throws IntrospectionException {
        ...
    }
