Subject [jira] Commented: (HARMONY-3103) [drlvm][build][kernel] kernel classes are always built w/o debug information
Date Fri, 02 Feb 2007 12:38:07 GMT

    [ https://issues.apache.org/jira/browse/HARMONY-3103?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12469733
] 

Alexei Zakharov commented on HARMONY-3103:
------------------------------------------

RI does include debugging info in its kernel classes. In DRLVM default behavior while building
natives is also to include debug symbols. So IMHO it is logical if DRLVM java kernel classes
are builded with debug information included.

> By default, DRLVM is built in debug mode, still DRLVM kernel classes are built w/o debug
information - this should be fixed.
> In particular, if stack trace contains the kernel classes, then no line information is
provided their. For example, stack strace from HARMONY-1930 has this issue (Class, Constrcutor
and ReflectExporter are kernel classes):
> java.lang.IllegalAccessException: A member of the "class cl2221" with "" modifiers can
not be accessed from the "class java.lang.Class"
>         at java.lang.reflect.ReflectExporter.checkMemberAccess(Unknown Source)
>         at java.lang.reflect.Constructor.newInstance(Unknown Source)
>         at java.lang.Class.newInstance(Unknown Source)
>         at testClassNewInstance.test(testClassNewInstance.java:15)
>         at testClassNewInstance.run(testClassNewInstance.java:35)
> =======================
> The file <trunk>/working_vm/build/make/targets/build.java.xml contains the line

>         <javac destdir="${java.build.dir}" source="${javac.source}"
>                 target="${javac.target}" debug="${java.debug.option}">
> which are supposed to build kernel classes in the mode defined in ${java.debug.option}.
Still this variable is not set properly.
> Foe now if one needs to build kernel classes in debug mode, then one needs to set true
to"'debug" in mentioned lines like:
>         <javac destdir="${java.build.dir}" source="${javac.source}"
>                 target="${javac.target}" debug="true">
> Thanks
