On Windows, when I install the JDK from Sun there's a file named
src.zip that contains Java source for the classes that normally come
with a Java runtime (for example, java.lang.String). I'm now trying
to do some Java development under Suse Linux. Using the package
manager, I've installed two different JDKs at

/usr/lib/jvm/java-1.6.0-sun-1.6.0.u11
/usr/lib/jvm/java-1.6.0-openjdk-1.2_b09

but I still can't find anything that looks like a runtime source jar [sic].

Surprising. When I installed the JDK from Sun on my Ubuntu Linux boxen it put
src.zip right in the installation directory, alongside LICENSE, README.html,
lib/, bin/ and the rest. It's done this for every version of the JDK I've
installed from Sun, at least as far back as the earliest Java 5 installs.

This is a problem because most of the problems I'm finding are
happening in the runtime but I can't usefully debug into them without
source code. How do I find this under Linux?

ever looking at the source for the native parts of the
runtime.

I suspect that the problems the OP is finding are not actually happening in
the Java libs. The Java libs are not bug-free, but they're pretty close in
practice. This leads me to conclude that the problems are not actually being
found.
