I'm facing repetitive messages like following on production application log file:

```
<Jul 13, 2018, 11:33:45,489 AM CEST> <Error> 
<oracle.adf.share.ADFContext> <BEA-000000> <ADFContext leak detected.
oracle.adf.share.ADFContext.setAsCurrent(ADFContext.java:1717)
oracle.adf.share.ADFContext.createDefaultContext(ADFContext.java:1337)
oracle.adf.share.ADFContext.getCurrent(ADFContext.java:1311)
oracle.adf.share.ADFContext.get(ADFContext.java:1607)
oracle.adf.share.jndi.MDSBackingStore.getMDSSession(MDSBackingStore.java:421)
oracle.adf.share.jndi.MDSBackingStore.isReadOnlyMDSStore(MDSBackingStore.java:197)
oracle.adf.share.jndi.MDSBackingStore.<init>(MDSBackingStore.java:153)

```

It's an ADF application developed on JDeveloper 12.2.1.3.0

I've tried to search this error but all I could find was:

* a bug issue (on Oracle Support, Doc ID 2321165.1) with solution saying that "these messages can normally be ignored" and that it was a BI bug problem, ADF just reporting that. (But I'm not using BI on this project)
* another site saying to modify logging level from Managed Server Log Configuration on Weblogic for class "oracle.adf.share.ADFContext" from INFO to FINEST. There's also [this question](https://stackoverflow.com/q/38629405/3690556) here on stakoverflow, but I cannot insert any comment (need 50 point reputation) and I'm not sure it's the same problem.

I'd try to modify log level, but I'm not sure of this. I can't figure out how an higher log level can solve the problem. And will this impact on performance?

Someone solved this problem before or has suggestions?

P.S.: This is my first question here. Let me know if I have to improve the question, thanks.
