SQL Developer generates strange trace files on server

Question

Hello out there,
I observed the generation of some strange trace files on the database server (Oracle 11.0.2.0.2 64bit on Win 2008R2).
Whenever I start SQL Developer (3.2.20.09.87 64bit with JDK 1.7.0_17 64bit on Win7 64bit) for each connection I defined one trace file like this is generated:
Trace file C:\ORACLE\diag\rdbms\ora\ora\trace\ora_ora_8500.trc
Oracle Database 11g Release 11.2.0.2.0 - 64bit Production

Breaking the connection before proto/dty negotiation, error raised 3113I enabled listener log to find out the origin of this and it contains lines like the following:

On other servers, similar trace files are generated, one for each connection in my SQL Developer.
This also occurred with JDK 1.6 so I don't think it's a Java issue.
Besides the generation of the trace files there seem to be no other problems.
Any ideas?

Hi,
I think Srini is probably correct. The noted bug applies to 11.2.0.1 and up, is fixed in 12c, and included in an 11.2.0.3 patch. However the version of SQL Developer also affects the creation of trace files on product startup (prior to any user initiated db connect attempts).
For example,
A. SQL Developer 3.1.07.42 - no such trace files created.
B. SQL Developer 3.2.20.09.87 - such trace files created for 11.2.0.1 connections, but not 10g XE or 12c connections.
So I presume an OCIServerAttach call got added in 3.2.2, not sure in support of which feature, but the bug will only impact users of 11.2.0.1, 11.2.0.2, and unpatched 11.2.0.3 DB releases.
