windows客戶端jprofiler連線遠端Linux Tomcat出現的破解身份驗證問題
jprofiler監控Tomcat，連線時出現錯誤提示：
The JVM might have terminated unexpectedly.
If the JVM has crashed,please try the following strategies:
* Reduce the -Xmx value of the profiled application
* Change your profiling settings(e.g. from dynamic instrumentation to sampling)
I tried for a long time not depriving the line,
Later, it found a close look at Terminal prompt "Invalid license key".

解決辦法
1、在windows端找到“C:\Users\xxx\.jprofiler7\config.xml” ，開啟此檔案
找到“<licenseKey name="lych" company="hkrt" key="[email protected]#24777-1i8da63tvtyl2#1119" />”拷貝到
linux環境中的目錄 \root\.jprofiler7\config.xml檔案中
找到改行<licenseKey name="" company="" key="" />
將此行改為： <licenseKey name="lych" company="hkrt" key="
2、修改TOMCAT啟動檔案catalina.sh，
新增：
JAVA_OPTS="$JAVA_OPTS -server -Xms2048m -Xmx2048m -XX:PermSize=256m -XX:MaxNewSize=512m -XX:MaxPermSize=512m -Djava.awt.headless=true"
JAVA_OPTS="$JAVA_OPTS -agentlib:jprofilerti=port=8849
config=/root/.jprofiler7/config.xml
3.重啟tomcat
4.windows jprofiler客戶端 重新連線linux ，成功！
