[ts-7000] TS-7300 JAVA Problem

["gcworrell" <>]

Problem :
When printing a float or double as a String, the resulting string
interpretation of the value is wrong (i.e. not close to the original
value) and it contains non-numeric characters.

Below is a session log that contains:
A cat of a simple program called WriteTest
The results of the execution of WriteTest
The results of java ?version

NOTES :
The value stored in the variable appears to be correct.  The actual
program I was running when I found this problem seems to receive the
correct double or float value when used in computations.  The error
appears to be in the toString() method.

I had originally installed the stable version of JamVM on the TS-
7300, but it had lots of problems.  At first I thought it was the
java application, but the same application has run without problems
on many other java runtimes, including the IBM j9 that I used on an
ARCOM Vulcan PC104 CPU.  One of the items that jumped out at me was
that the file separator was coming up as a ":" instead of a "/". 
Once I saw that, I installed the testing version of JamVM.  Now
everything works correctly except the items noted here (or at least
I should say I haven't found any other problems).  I also tried
SableVM.  It performed exactly the same.

I've run the WriteTest application on several other platforms with
different runtimes, and it works correctly on all.

I've submitted this as a bug report to the Debian folks and have
recieved no reply.



Thanks for any help.  I'm busy trying work-arounds, such as :
(new Double(doubleValue)).toString()
But that produces the same results.

Please contact me if you need any additional information.  I'll be
in a real Jam (no pun intended) if I can't get this to work.
