> Hello Olingo community,
> we have an issue when sending multiple queries packed in batch request. Often
> upon restart of our application (when the caches are empty), the first
> execution of a particular batch request which contains quite a number of
> queries we are getting one of the following errors (most of the time the
> first one):
> {color:#d04437}!/jira/images/icons/emoticons/error.png! You have attempted
> to set a value of type class java.lang.String for parameter 5 with expected
> type of int from query string {color}
> {color:#d04437}SELECT E1 FROM CreditProduct E1 WHERE
> (((E1.creditProductPk.creditAgencyId = ?2) AND ((E1.creditProductTypeCode =
> ?5) OR (E1.creditProductTypeCode = ?8))) AND (E1.isDeactivated =
> false)).{color}
> {color:#d04437}!/jira/images/icons/emoticons/error.png! Query argument 33
> not found in the list of parameters provided during query execution.{color}
> {color:#d04437}!/jira/images/icons/emoticons/error.png! While trying to
> invoke the method java.lang.String.contains(java.lang.CharSequence) of a null
> object returned from
> org.apache.olingo.odata2.jpa.processor.core.ODataParameterizedWhereExpressionUtil.getJPQLStatement(){color}
> {color:#d04437}!/jira/images/icons/emoticons/error.png! Query argument 3 not
> found in the list of parameters provided during query execution.{color}
> {color:#333333}It looks like that the issue could be in class
> {color}*ODataParameterizedWhereExpressionUtil* where the
> *parameterizedQueryMap* is defined. It is defined as static and it looks like
> a concurrency issue. Is there a reason behind defining this map as static? It
> seems very similar to the already opened issue OLINGO-1254
> As soon as the queries runs one time and the caches are filled we don't have
> it anymore unless the app is restarted.
> Could you please assist us with finding a solution here?
> Thank you,
> Milko
