I've been trying to improve this somewhat, but there are a few issues that need to be addressed. 1.9 interpreted mode has some bad Spec failures. Most of them are encoding-related. I've identified a few (JRUBY-6183 to JRUBY-6188) and tagged them (f1a5b6b). spec:ci_precompiled_18 is failing because there is not enough heap is allocated. (http://ci.jruby.org/job/spec-ci/label=master,testtype=spec-ci_precompiled_18/1339/console) I tried to tweak a few things, but I have been unsuccessful. (I even tried exporting JAVA_OPTS='-Xmx1024m'.) Does anyone have a brilliant idea? Often times, 1.8 spec runs end up failing with a single failure. For example, http://ci.jruby.org/job/spec-ci/label=master,testtype=spec-ci_compiled_18/1332/console http://ci.jruby.org/job/spec-ci/label=master,testtype=spec-ci_interpreted_18/1336/console I've made an attempt (5907d5d).
