If utPLSQL encounters ORA-04068 or ORA-04061, it will immediately abort test execution and re-raise the exception.

This mechanism is implemented deliberately as supressing this exceptions makes the session unable to re-validate the invalid package state.
If ut_executable would suppress those exceptions, consecutive calls to ut.run() would still end with invalid package state.

When running a suite of more than one test package, the side effect is that not all tests get executed and the results are partly presented on the outputs as the execution is aborted.

As an alternative the framework could flag such exceptions when they occur, so it can continue with execution for the remaining of unit test packages.
If the exception was flagged, the framework would throw an exception after the execution.
That way we allow the session to recover from invalid package state and still run a full suite.
