RFR: 8269336: Malformed jdk.serialFilter incorrectly handled [v2]

[Jaikiran Pai]

> Can I please get a review for this change which addresses https://bugs.openjdk.java.net/browse/JDK-8269336?
> 
> As noted in that issue, this change will now propagate any exception that occurred during parsing and creation of the filter configured through the `jdk.serialFilter` system property. It will also continue to log those errors, like it previously did.
> 
> A new jtreg test has been introduced to reproduce this issue and verify the fix. 
> 
> Given that invalid values for this system property will now start throwing exception, will this change need a CSR?
