Resolving connections errors on oci8 in jdeveloper 11gR2

Got a fresh jdev 11gR2 (11.1.2.0.0, studio) on an existing oracle client home 11.1.0.6.0 and tried to create a connection to an oracle database based on the oci8 option (thick instead of thin driver) in the Create Database Connection dialogue. The result on some test (test connection button) was a:

Test failed: oracle.jdbc.driver.T2CConnection.getLibraryVersionNumber()I

The resolution trick seems to comprise of a copy of the ojdbc6.jar of the oracle client installation, here in d:\Programme\Oracle\product\11.1.0\client_1\jdbc\lib\, to the jdeveloper app server lib path, here in d:\Programme\Oracle\Middleware\wlserver_10.3\server\lib\.

My reference to the problem solution was: this thread entry on the oracle forums.
