Application logging in weblogic 12c messed up after upgrading Jdeveloper from 12.1.2 to 12.1.3

Question

We recently upgraded JDeveloper from 12.1.2 to 12.3. Application logging has messed up since then. App works but the log is filled up with below messages. Any help on this is highly appreciated.

Answer 1

there is a bug filed for this in Oracle Support site "Bug 19483893 : WHEN MULTIPARTCONFIG SUPPORT IT'S ENABLED, FILLS LOG WITH WARNING MESSAGES"

"So in summary, issue relates only to the massive warning messages appearing on log. There is no broken functionality at all with any patch. Just seems to be that some piece of code added an extra warning message which was not previously part of the product, which causes issues for customers."

It seems that there is no resolution for that, apart from ignoring (or you can apply a log filter at server logging framework level)

Answer 2

I'm facing the same <Warning> on weblogic server 12.1.3 and primefaces 5.1.x JSF webapplication.
WebApp has no errors. It is working with no problems.
On wls 12.1.2 there are no such Warnings.
