This is a vote to release Commons Math 1.2.
I assume the SVN tag is:

Could not find any details on which Java releases are supported.
The front page says:
"No external dependencies beyond Commons components and the core Java
2 platform."
AFAIK this merely implies Java 1.2+; however the jar manifests show
version 1.3. It would be helpful if this was clearly stated on the
web-site.
I've tried building the code using Java 1.3.2_20 and Ant, however the
tests fail with:
internal-test:
[junit] Using loader null on class
org.apache.tools.ant.taskdefs.optional.junit.XMLJUnitResultFormatter:
java.lang.NoClassDefFoundError: org/w3c/dom/Node
This seems to be a problem with running ant itself, not [math] which
does not deal with xml.
The Ant build works OK on Java 1.4.2_16, however the generated jar
file manifest is rather minimal; it should have more info.
The Maven 1 build seems to work OK on 1.4, however the generated jar
file contains two copies of META-INF/LICENSE.txt.
The Maven 1.0.2 build seems to work OK on Java 1.3, however the test
suite seems to stall when running the test:
org.apache.commons.math.ode.GraggBulirschStoerIntegratorTest
I suspect the following ones are related to the known wrong behaviour of
Math.cos prior to Java 1.4 (see
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4345903). These tests
also correspond to corner-case behaviour (dealing with infinity and NaN)
where this version of JDK had issues.
I don't know if the previous case is similar or not. There is a simple
unprotected loop in these tests cases which involves cosines and sine.
It is in the TestProblem3.computeTheoreticalState() method. Could you
change the loop from:
do {
// some computation about Kepler equation
} while (Math.abs(corr) > 1.0e-12);
to
corr = 999.0;
for (int i = 0; (i < 50) && (Math.abs(corr) > 1.0e-12); ++i) {
// some computation about Kepler equation
}
and check if the test exits ?

If this test is commented out, then all the other tests complete,
however there are several errors.
The failures appear to be:
