Subject [jira] Commented: (HARMONY-4308) [buildtest][vts] Test vm/jvms/classFile/structure/accessFlags/accessFlags08/accessFlags08.xml corresponds 1.4 specifications
Date Wed, 15 Aug 2007 13:11:31 GMT

    [ https://issues.apache.org/jira/browse/HARMONY-4308?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12519955
] 

Pavel Pervov commented on HARMONY-4308:
---------------------------------------

The fact is this test is against 1.4 specification. Java 5 must behave as Java 1.4 in case
it is passed 1.4 class file. So, this is the bug in DRLVM rather than the bug in test.

Please, change bug description to "[drlvm][classloader] Test vm/jvms/classFile/structure/accessFlags/accessFlags08/accessFlags08
fails due to incorrect processing of accesss flags in 1.4 class files"

> [buildtest][vts] Test vm/jvms/classFile/structure/accessFlags/accessFlags08/accessFlags08.xml
corresponds 1.4 specifications

>             Project: Harmony

> 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.
