| >Description:
|       There is still no SVR4 compat support for this architecture.
| 
|       It would be very niche to have that in order to run Solaris X86 
binaries on a NetBSD system.
| 
|       My concrete problem is, that the JRE for linux (64 and 32) bit will not 
work reliable in the
|       linux or linux32 emulations. There seems to be a timing problem during 
startup of the engine,
|       so that it will crash most times. If the machine-code-compiler is 
deactivated on the command line
|       for the java program, the JRE comes up most times - still not all the 
times.
|       I simply hope that JRE would run much more stable on Solaris as it does 
on any Linux and that
|       it would work in the emulation too.
|       At the moment it is impossible to run a JRE on a NetBSD-5.0.2-amd64 
system in a reliable way.
| 
|       A quick-try from my side by just enabling the SVR4 compat in an amd64 
kernel shows, that
|       (at least) some lines in files.amd64 are missing (see below) and that 
the machine dependen headerfiles
|       svr4_machdep.h and svr4_32_machdep.h must be written.
| 
|       "missing" lines in files.amd64:
| # SVR4 binary compatibility (COMPAT_SVR4)
| include "compat/svr4/files.svr4"  
| # file    arch/i386/i386/svr4_machdep.c           compat_svr4
| # file    arch/i386/i386/svr4_sigcode.S           compat_svr4
| # file    arch/i386/i386/svr4_syscall.c           compat_svr4
| 
| # SVR4 binary compatibility (COMPAT_SVR4_32)
| include "compat/svr4_32/files.svr4_32"  
| # file    arch/i386/i386/svr4_machdep.c           compat_svr4_32
| # file    arch/i386/i386/svr4_sigcode.S           compat_svr4_32
| # file    arch/i386/i386/svr4_syscall.c           compat_svr4_32
|       END of missing lines
| 
|       Accedently my knowledge about the stack-frame differences of 32 and 64 
bit Intel-CPU's is nearly zero.
|       So I cannot guess a valid svr4_*machdep.h file and try if the rest of 
the emulation is already working.

Is there a place to download solaris binaries so we can test?

Also the linux emulation works much better in NetBSD/current and also you
can build native java binaries using the OpenJDK.
