AW: [eclipselink-dev] WG: @QueryHint(name = QueryHints.QUERY_RESULTS_CAC

["Goerler, Adrian" <adrian.goerler@xxxxxxx>]

Hi Tom,


it turned out that the issue is caused by the properties

test.agent=-Dignore
test.weaving=-DTEST_NO_WEAVING=true.


If I remove these properties, I get a clean test run. 

Kind of strange that the query cache requires weaving.

Also, it worked before. There must be some regression.

Hi Tom,

I am running on trunk. Freshly synched and built.

These are my test.properties:

---snip---
jdbc.driver.jar=W:/SVNS/extension.lib.external/mysql-connector-java-5.1.8-bin.jar
db.driver=com.mysql.jdbc.Driver
db.url=jdbc:mysql://localhost/EL
db.user=me
db.pwd=abcd1234
db.platform=org.eclipse.persistence.platform.database.MySQLPlatform


test.agent=-Dignore
test.weaving=-DTEST_NO_WEAVING=true
server.weaving=false

server.name=netweaver
---snap---

Any idea what's wrong?

-Adrian

Hi Adrian,

   Exactly what version are you running on?  Have you done anything special to 
the configuration?  The nightly tests, and my local run both pass that test.
