J2SE : FAIL - JDK 7 b06, PASS JDK 7 b05
Platform[s] : FAIL SUSE 10 PASS SUSE 9

Then I try to use plugin jdk1.7.0/jre/plugin/i386/ns7/libjavaplugin_oji.so from JDK 7 b06 on SUSE 10 all attempts to open any applet finish with the message

Could not read ack from child process
Plugin: Java VM process has died.
plugin: java process exited with status 6
Could not start JavaVM!

with creation of plugin.stack.trace

java.lang.NullPointerException

The same works on SUSE 9 and with JDK 7build 05.
