JIT on Netwinder

[Sergey Voitseh]

Hi Godmar!
     I've determine a problem with Illegal Instruction but have another one.
When I try to run java with simple helloworld class or javac with out parameters
I get as a result following:
> java Hello
kaffe:memory violation at pc = 0x02148840, lr=0x4009c008 (bad adresses =
0x00000001? code 3)
Internal error: caught an unexpected exception.
Please check your CLASSPATH and your installation.
java/lang/NullPointerException
        at java.util.HashMap.bucket(HashMap.java:245)
        at java.util.HashMap.put(HashMap.java:107)
        at java.util.Hashtable.put(Hashtable.java:106)
        at java.lang.System.initProperties(System.java:native)
        at java.lang.System.<clinit>(System.java:47)
Aborted

It seems that it failed when calling InitThreads from initialiseKaffe.

The same results I had when configured and compiled with next parameters:
     ./configure --prefix=/usr/ --with-threads=unix-pthreads --with-engine=jit
     ./configure --prefix=/usr/ --with-threads=unix-jthreads --with-engine=jit

Best regards,
Sergey

 This could either be a problem with cache flushing (shouldn't be though)
or a problem with the compiler you're using.

You could try compiling with a different level of optimization
and you should doublecheck that the D-Cache is being flushed properly.
