I've just run Mauve against both the 4.3 tree and our Classpath 0.98 merge tree (effectively equivalent to Classpath CVS + GCJ-specific changes). Overall: 4.3: 281 of 3177 tests failed. 123926 total calls to harness.check() failed. 4.4: 239 of 3177 tests failed. 143832 total calls to harness.check() failed. There will be some new tests that compile with 4.4 but not 4.3 (e.g. java.util.Scanner tests). Additional FAILs are as follows: +FAIL: gnu.java.security.util.TestOfIntegerUtil +FAIL: java.sql.Date.DateTest +FAIL: java.lang.Character.Blocks15 +FAIL: java.lang.InheritableThreadLocal.simple +FAIL: java.text.SimpleDateFormat.parse +FAIL: java.util.Calendar.ampm +FAIL: java.util.Scanner.LotsOfPMInts +FAIL: java.util.Scanner.Inputs +FAIL: javax.swing.text.DefaultStyledDocument.ElementBuffer.insert +FAIL: javax.swing.table.JTableHeader.AccessibleJTableHeader.AccessibleJTableHeaderEntry.getForeground The two Scanner tests we can discount as regressions as they simply won't have run with 4.3. The remaining failures: FAIL: gnu.java.security.util.TestOfIntegerUtil line 71: IntegerUtil.valueOf(String) MUST be faster than Integer.valueOf(String) [1] -- boolean passed to check was fa\ lse FAIL: java.sql.Date.DateTest uncaught exception: java.lang.OutOfMemoryError FAIL: java.lang.Character.Blocks15 uncaught exception: java.lang.OutOfMemoryError FAIL: java.lang.InheritableThreadLocal.simple Test timed out.

OpenJDK can't compile it. CACAO + Classpath CVS also fails with java.text.SimpleDateFormat.parse, java.util.Calendar.ampm and javax.swing.text.DefaultStyledDocument.ElementBuffer.insert, which suggest a common Classpath issue. java.sql.Date.DateTest, java.lang.Character.Blocks15, java.lang.InheritableThreadLocal.simple and javax.swing.table.JTableHeader.AccessibleJTableHeader.AccessibleJTableHeaderEntry.getForeground are all GCJ-specific failures. OpenJDK passes all but the first, which is GNU Classpath specific.
