The src/share/test/serialization and src/share/test/ververify directories
contain old (pre-jtreg) serialization tests, some of which no longer
compile with 1.4.x javac (due to illegal import statements which were
tolerated by earlier versions of javac). These tests should either be
ported to jtreg (and moved into test/java/io/Serializable) or removed
as appropriate.
