EnvironmentManager.py:122: raise InvalidVMError("Unable to determine valid vm. Please see http://www.gentoo.org/doc/en/java.xml#doc_chap4") The link http://www.gentoo.org/doc/en/java.xml#doc_chap4 redirects to https://wiki.gentoo.org/wiki/Java#doc_chap4 but the page probably changed its anchor naming because 'doc_chap4' doesn't appear in the source. https://wiki.gentoo.org/wiki/Java#Compilers appears to be the correct link.
Actually, now that I understand the error from 572944 I think the correct section to link to is https://wiki.gentoo.org/wiki/Java#Setting_a_default_virtual_machine
Indeed this link is no longer valid and must be changed.
Wiri is no longer handled via bgo. Closing.
