- Subject: committed: jcf-dump support for SourceDebugExtension
I checked this into mainline.
JSR 45 defines a new "SourceDebugExtension" attribute
(which Kawa implements).
This patch adds supports to this attribute.

if HANDLE_SOURCEDEBUGEXTENSION_ATTRIBUTE is defined.
* jcf-dump.c (HANDLE_SOURCEDEBUGEXTENSION_ATTRIBUTE): Print contents.
