[JGIT] maven build fails on OS X

I don't know if this is known about - I get failures running the m2
build for jgit:

Failed tests:
  testParse_implicit_mixed_encoded(org.spearce.jgit.revwalk.RevCommitParseTest)
  testParse_explicit_bad_encoded(org.spearce.jgit.revwalk.RevCommitParseTest)
  testParse_implicit_mixed_encoded(org.spearce.jgit.revwalk.RevTagParseTest)
  testParse_explicit_bad_encoded(org.spearce.jgit.revwalk.RevTagParseTest)
  testDequote_OctalAll(org.spearce.jgit.util.QuotedStringGitPathStyleTest)
  testDequote_Latin1(org.spearce.jgit.util.QuotedStringGitPathStyleTest)
  testDequote_RawLatin1(org.spearce.jgit.util.QuotedStringGitPathStyleTest)
  testGetText_DiffCc(org.spearce.jgit.patch.GetTextTest)

Curiously, the tests work in eclipse and from ./make_jgit.sh - I
suspect some environment setting with the mac's charset.

I can try and fix it if it's new, but I wanted to check first..
