Did you try utilizing the files in this technote: Configure Report designer (Eclipse) for Maximo 7.6.1.x (ibm.com)
We develop for customers on 7.6.1 and 7.6.0 and have a similar config for both which works for us but we almost exclusively develop reports on SQL Server/DB2. I would be surprised if you couldn't connect to 12c with the driver they attached as 12c was supported for later 7.6 versions and all of the 7.6.1 versions. It's honestly not something I've tested but I will if you're still having issues.
For running it as Java 1.7, if you don't want to install an unsupported Java version like this on your machine, you might be able to do what we do which is run the IBM Java SDK (which has an extractable option without installing) and then specify the -vm argument prior when running BIRT. For example, I've pasted a snippet of our bat file we use to launch it.
start %BIRTdir%\eclipse431\eclipse.exe -vm %BIRTDir%\java_1.7_64\bin\javaw.exe -vmargs -Xmx512m
Getting the version for Windows is more complicated because they don't make that readily available like they do for Linux systems. We previously downloaded it from the Eclipse Development (Java SDK downloads, Eclipse (ibm.com)) but that has been updated to 1.8. If nothing else, you could have both java versions installed and then use something similar to utilize the proper 1.7 Java runtime but that's obviously not entirely ideal.

Subject: BIRT 431 preview: Java/JDBC for Oracle compatibility issue
Maximo 7.6.1.2; BIRT 431; Oracle 12c
I want to preview my reports (by connecting from BIRT to the Maximo database).
If I understand correctly, BIRT 431 requires Java 7. Yet, the latest version of JDBC for Oracle requires Java 8 (older drivers won't connect to the database).
If that's correct, then how can I preview BIRT reports if BIRT 431 doesn't support any functioning JDBC drivers?
(I'm new to BIRT, so please feel free to correct any inaccuracies.)
