Loop over indexed strings: Java compilation warning

[gustavo_mindreau]

Hello,
Working with indexed strings I noticed a Java compilation warning (java "1.8.0_152") in NetRexx (3.07),

        Program test.nrx
          === class test ===
            function main(String[])
        Note: /test.java uses unchecked or unsafe operations.
        Note: Recompile with -Xlint:unchecked for details.
        Compilation of 'test.nrx' successful

I do not remember getting this in the previous release (3.06).
I reproduced this with the standard example from the NetRexx Language Reference (page 88).

        ------------------------------------------------------------------------------------------------
        Class test public

        Method main(args=String[]) public static

          mycoll          = ''
          mycoll['Tom']   = 1
          mycoll['Dick']  = 2
          mycoll['Harry'] = 3

          Loop name over mycoll
           Say mycoll[name]
           end
        ------------------------------------------------------------------------------------------------

Comments and/or suggestions are welcome.

Hi Gustavo,

this is a message from the Java compiler, not NetRexx.

Yes, but the NetRexx compiler's job is to ensure there are no messages from the Java compiler ...

Hi Mike,

true, but in some cases, generics come to mind, java has changed its attitude on what is desirable; we could suppress these messages (as was done sometimes); I need to have a closer look at what particular deprecation is flagged here.

best regards,

René.

:-)   Yes .. I often have similar problems with GCC .. something that was fine before now raises a warning.   Since I only accept clean compiles (no warnings or errors) in my code, sometimes some quite big reworking is needed.   <sigh>
