I work on a java applet and I would like it to be compatible with the
old Microsoft JVM on Win2000 for example. Now the MS JVM doesn't
support some functions in the String library, like split() and
compareToIgnoreCase(). No problem, but I would like to know which
functions are not supported. I cannot find the information on the
internet and my compiler doesn't complain if I use unsupported
functions (Eclipse, set to compiler compliance level set to 1.3).
It's 1.1.4 to be exact. However, jview has deviations from Java and, of course, its own bugs.
Microsoft do not appear to have patched security vulnerabilities in jview for some considerable time. Indeed, Sun's JRE 1.1 has completed its end-of-life period. From the achive page:
"[...] These products are down-revision products that may have various bugs, Y2000, and possibly security issues associated with them. Sun in no way recommends these products be used in a live, production environment. Any use of product on this page is at the sole discretion of the developer and Sun assumes no responsiblity for any resulting problems."

In my view, deliberately allowing a public applet to function on 1.1 indicates condonation of running an insecure machine. Such a compromised machine could potentially used to attack other machines or to capture data passing though it, such as confidential bank login details.
About the only use for 1.1 applet code is to warn the responsible party to upgrade (or remove) their JVM.
