Answer 1

不能只杀死进程的一个线程，如果使用命令“kill -9 threadNo”，就会杀死进程。

Answer 2

Find java process using below

$ ps -fea | grep -i java

Here is the sample output

user 2895 8191 0 09:28 pts/1 00:00:00 grep -i java
user 4610 4607 1 Aug29 ? 01:40:00 /home/user/Software/java-7-sun/bin/java -Dosgi.requiredJavaVersion=1.6 -Xms40m -Xmx768m -XX:MaxPermSize=256m -jar /home/user/Software/springsource/sts-3.3.0.RELEASE//plugins/org.eclipse.equinox.launcher_1.3.0.v20130327-1440.jar

and then kill the process

$ kill -9 4610

As you want to automate this via Shell, to get pid, further search in the text with your specific java app (probably search location of app)

ps -ef | grep java | grep -v grep

Extract PID portion using SED
