Re: Porting Sable VM to SH4

Hello,

The problem is solved by adding 
--property="java.library.path=/usr/local/sablevm/lib/sablevm-classpath" 
as command line argument when invoking the sablevm command. I guess the 
internal java.library.path was wrongly configured somewhere along the 
road. When I compile a simple test program, it runs now.

However, my main goal was to get an OSGI framework (more specifically 
knopflerfish) running on my target sh4 machine. When starting the 
framework, it loads, but I do (sometimes) get an error when installing 
some extra bundles. As it does seem more VM related than OSGI related, I 
thought someone here might know what causes this error. The weird thing 
is, it does not always occur, so my guess is it has something to do with 
Thread scheduling:

Anyone who knows the cause of this error (or even better: a solution)?

Cheers,
