I am running simulated business application users on JDK 5.0 to compare response times between server and client switches. The application is running on JServ with 3 concurrent users for 40 minutes. The performance of server JVM is better than client JVM. However, the jstat -compiler option is showing that several methods are failing to compile.

Here is the output for jstat -compiler at end of test with -client switch:
Compiled Failed Invalid Time FailedType FailedMethod
    7134 0 0 10.48 0

Here is the output for jstat -compiler at end of test with -server switch:
Compiled Failed Invalid Time FailedType FailedMethod
    3592 205 0 180.94 1 oracle/apps/fnd/framework/webui/OASpacerHelper setMetaDataProperties


As you can see 205 methods failed compilation. The JVM did not crash during the test.
