hello John,
first check that you have installed the solaris sparc 64-bit packages
(if you use the sparc platform) in addition to the sparc 32-bit packages
(you may check that you have the 64-bit binaries in the
$JAVA_HOME/bin/sparcv9 directory, and in $JAVA_HOME/jre/bin/sparcv9,
plus libraries in $JAVA_HOME/jre/lib/sparcv9).
the binary $JAVA_HOME/bin/java is a 32-bit wrapper that will launch the
64-bin binary.
#truss -t exec $JAVA_HOME/bin/java -d64 -version
execve("/usr/jdk/instances/jdk1.6.0/bin/java", 0xFFBFFDEC, 0xFFBFFDFC)
argc = 3
execve("/usr/jdk/instances/jdk1.6.0/bin/sparcv9/java", 0x0002B170,
0x0002BE30) argc = 2
java version "1.6.0"
Java(TM) SE Runtime Environment (build 1.6.0-b105)
Java HotSpot(TM) 64-Bit Server VM (build 1.6.0-b105, mixed mode)
so you can see that the 64-bit binary is launched:
/usr/jdk/instances/jdk1.6.0/bin/sparcv9/java
greetings,
Stoyan
