     Javasoft1.2_i386 FAIL JDK-1.2-V

Each test was run 50 times with each JDK and they all passed or failed all 50 times.

It fails using JTG 1.2 with the following error

Exception in thread "main" java.lang.IndexOutOfBoundsException

On Javasoft 1.2 intel it fails with an error of

Exception in thread "main" java.lang.IndexOutOfBoundsException

        at java.io.StringBufferInputStream.read(Compiled Code)

        at X.f1(Compiled Code)
