           Summary: jamvm generates "Illegal Instruction" when jar file is
                    executed on EDB9301
           Product: Openembedded
           Version: org.openembedded.dev
          Platform: ARM
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: critical
          Priority: P3
         Component: Java
        AssignedTo: openembedded-commits at lists.openembedded.org
        ReportedBy: tk at ecocoms.com

I use Openembedded to create file system for EP9301 Cirrus Arm based Board
Compatible with original Cirrus EDB9301.

My OE config file looks like this:

--------------------------------------------------------------------------
PREFERRED_VERSION_linux = "2.6.32"

################ jamvm ######################
PREFERRED_PROVIDER_virtual/java-initial = "jamvm-initial"
PREFERRED_VERSION_jamvm-initial = "1.4.5"
PREFERRED_VERSION_classpath-initial = "0.93"

############## native versions #############
PREFERRED_PROVIDER_virtual/java-native = "jamvm-native"
PREFERRED_VERSION_jamvm-native = "1.5.3"
PREFERRED_VERSION_classpath-native = "0.98"

############# ecj bootstrap ################
PREFERRED_VERSION_libecj-bootstrap = "3.4"

############ javac native ##################
PREFERRED_PROVIDER_virtual/javac-native = "ecj-bootstrap-native"
#PREFERRED_PROVIDER_virtual/javac-native = "openjdk-javac-native"

############### target versions #############
PREFERRED_VERSION_jamvm = "1.5.0"
PREFERRED_VERSION_classpath = "0.98"
PREFERRED_VERSION_classpath-minimal = "0.98"

PREFERRED_PROVIDER_classpath = "classpath-minimal"

MACHINE = "ep93xx"
TARGET_OS = "linux-uclibc"
DISTRO = "minimal-uclibc"
---------------------------------------------------------------------------

The result is cross compiled jamvm and classpath
when run on the target jamvm generate help normaly

# jamvm -help

when run with jar file

# jamvm -jar test.jar

an Illegal instruction is reported

After little digging I found that for jamvm-1.5.0 in the file

class.c 

in line 229
the Illegal Instruction is generated by:

memcpy(buff, ptr. length);


with hope to be useful

Sincerely Yours
Todor
