Subject Re: [jira] Created: (HARMONY-2544) [drlvm][jvmti] Check of settable system properties
Date Fri, 15 Dec 2006 12:25:05 GMT
I could argue with Pavel that we have to have read only system properties
which cannot be set from JVMTI. The specification doesn't say that it is
necessary to have read only properties, it just mentions that
SetSystemProperty may return an error
a property is not writable. But which properties are writable or not
not specified.

>From the patch it seems Sun doesn't allow JVMTI to set java.vm.vendor,
java.vm.version, java.vm.name and java.vm.info. But I don't really like to
disallow things for no apparent reason. So my question is, should be have
read only properties like Sun? What do you think?
