Through a recent change in https://bugs.openjdk.org/browse/JDK-8322983, the test/hotspot/jtreg/ProblemList-Virtual.txt problem listing file was updated to add a couple of entries for runtime/classFileParserBug/TestEmptyBootstrapMethodsAttr.java and runtime/logging/LoaderConstraintsTest.java tests.

These 2 entries are considered malformed because the bug ids they refer to aren't in the expected format (they currently contain a JDK- prefix). This should be fixed.
