Starting with Java version 220.127.116.11 Matterhorn stops working. This basicall measn that if someone (especially a new user) tries to install MH on a new system it will most likely fail since 18.104.22.168 is (at least) the default JDK-1.7 version for Scientific Linux and Fedora (and thus probably also the default for a lot of other distributions).
Some details about the defect was discussed on the matterhorn-users list:
Of the suggestions, I tried…
…adding -Djdk.logging.allowStackWalkSearch=true which did not help…
…and I tried updating the cxf.bundle. Version 2.2.9 is the version currently used by MH. With versions >= 2.6.0 MH starts to throw build errors. With 2.5.10 MH compiles but throws runtime errors (missing dependencies).
Also as Karen pointed out, the current version has a critical security vulnerability: http://cxf.apache.org/cve-2012-5633.html
@Tobias: If I interpret your mail correctly, you were the one who integrated cxf into MH. Thus I assignt his issue to you. If not, feel free to assign this to someone else.
