Cocoon 2.1.9 starts and seems to work normally on Harmony (IBM VME + Classlib).
Known issues:
Compiled code (up to version 2.0.4) can be downloaded from Cocoon site or built using RI compiler (any version).
I have run the htmlunit tests on RI, Harmony Classlib + DRLVM and Harmony Classlib + IBM VME. One test (org.apache.cocoon.CachingPipelineTestCase) hangs on all implementations, so it was excluded. 48 tests have been run. The results are:
3 test failures on RI:
2 FileNotFoundException-s + 1 unexpected return result,
9 failures on Harmony classlib + IBM VME:
3 noted errors + 6 errors related to JPEG and PNG representation,
24 failures on Harmony classlib + DRLVM:
9 noted errors + 15 more errors. Some of them, look like this "java.lang.RuntimeException: unexpected java.lang.ClassNotFoundException: inv8" where 8 changes to another integer values in different failures. And some look like:
org.apache.cocoon.ProcessingException: Sitemap: error calling function 'do_a'.
