Cloned from: 392995: [DB] ClassCastException when starting CDO Server recovering from crash, with Oracle DB

Patch

When starting the CDO Server and it detected it was crashed last time (because it was not stopped gracefully), a ClassCastException is thrown when using an Oracle DB:

java.lang.ClassCastException: java.math.BigDecimal cannot be cast to java.lang.Integer
 at org.eclipse.emf.cdo.server.internal.db.MetaDataManager$1.handle(MetaDataManager.java:356)

I'm not sure if it is supposed that the array has 2 BigDecimal values instead of an Integer and a Long (positions 1 and 2, respectively), when using Oracle. Maybe there is some wrong mapping somewhere. But if it's supposed to be like that, then I propose to change the code to parse the Integer and Long from the toString() result of each value, instead of try to make a cast.

Attached a patch with this change, that was tested with H2 and Oracle.
