> URL: https://issues.apache.org/jira/browse/HARMONY-4308
> Project: Harmony
> Issue Type: Bug
> Components: DRLVM
> Reporter: Vera Petrashkova
> Assignee: Gregory Shimansky

> According to the test description
> vm/jvms/classFile/structure/accessFlags/accessFlags08/accessFlags08.xml
> "Checks that VM loads class with ACC_PUBLIC, ACC_FINAL flags set and all unused
> (reserved) bits set to 1. Positive test."
> this test uses access flags xF9DF and expects that VM does not throw ClassFormatError because
> 1.4 spec defines the following flags
> ACC_PUBLIC = 0x0001
> ACC_FINAL = 0x0010
> ACC_SUPER = 0x0020
> ACC_INTERFACE = 0x0200
> ACC_ABSTRACT = 0x0400
> and says that If the ACC_INTERFACE flag of this class file is not set, it may have any of the other flags.
> And all bits of the access_flags item not assigned in spec are reserved for future use.
> They should be set to zero in generated class files and should be ignored by JVM implementations.
> But 1.5 spec defines new access flags ACC_ANNOTATION = 0x2000 and ACC_ENUM = 0x4000 and it says
> that if the ACC_ANNOTATION flag is set, the ACC_INTERFACE flag must be set as well.
> As the result this test fails with ClassFormatError: annotation type must be interface
> Used access flags should be fixed according to 1.5 specifications or this test should be removed.
> Tests from accessFlags015, accessFlags18 and accessFlags19 subsuites check the using of ACC_ANNORATION flag.
