Hi All,
I'm running 4.5-stable (last updated on April 30) and am getting
SIGBUS's with the new linux-ibm-jdk1.3.1 port. The problem only
occurs when running as an ordinary user, when running the jvm
as root, there's no problem.
Both 1.3.1 and 1.3.1_1 both show the same behaviour. 1.3.0 on the
other hand, works fine.
I can duplicate the problem by simply -
$ type java
java is /usr/local/linux-ibm-jdk1.3.1/bin/java
$ java
Bus error
$ su
# type java
java is /usr/local/linux-ibm-jdk1.3.1/bin/java
# java
Usage: java [-options] class [args...]
(to execute a class)
or java -jar [-options] jarfile [args...]
(to execute a jar file)
where options include:
-cp -classpath <directories and zip/jar files separated by :>
set search path for application classes and resources
-D<name>=<value>
set a system property
-verbose[:class|gc|jni]
enable verbose output
-version print product version
-showversion print product version and continue
-? -help print this help message
-X print help on non-standard options
Here's a relevant snippet from linux_ktrace -
