i get some java.lang.NoClassDefFoundError.

[itgo067]

First, before the first java.lang.NoClassDefFoundError happen, the spring boot project run well.
but when it happend, all requests become error. Not only spring's class , also my own java classes.

I'm using spring boot 1.4.3 version. and jetty replace tomcat-embedded.

error info like this

[wilkinsona]

Unfortunately, a couple of stack traces doesn't give us enough information to be able to help you. Can you please provide a small sample that reproduces the problem?

[itgo067]

I'm so sorry for this. I can't find out why or when it happens. I just catch some stack traces. I guess if this happens because of my jvm parameters .

-XX:MetaspaceSize=64m -Xms400m -Xmx400m -Xmn300m -Xss228k -XX:SurvivorRatio=4 -XX:MaxTenuringThreshold=15 -XX:+UseParallelGC -XX:ParallelGCThreads=2 -XX:+UseParallelOldGC -XX:MaxGCPauseMillis=2000 -XX:+PrintGC -XX:+PrintGCDetails -XX:+PrintHeapAtGC -XX:+PrintGCDateStamps -XX:+PrintGCTimeStamps -XX:+PrintGCApplicationStoppedTime -XX:+PrintGCApplicationConcurrentTime -Xloggc:/root/gc.log -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=/root

And the jdk version is

java version "1.8.0_101"
Java(TM) SE Runtime Environment (build 1.8.0_101-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.101-b13, mixed mode)

This is a complete stack info.

I doubt that those JVM parameters are causing the problem. Sorry, but we're going to need more information to be able to help you with this

[itgo067]

I'm using aliyun cloud service . the ecs enviroment is 1Cpu 1G. if you can tell me something wrong with my JVM paramters?

[wilkinsona]

As I said above, I don't think there's anything wrong with your JVM parameters. Surely there's more information that you can provide? You haven't even told us how you're running your application or what version of Spring Boot you're using. If you want us to spend some time trying to help you, then you're going to have to spend some time providing as much information as possible.
