Notes

• You can select either SerialGC (UseSerialGC) or G1GC (UseG1GC) as the GC for Application Server. Do not specify the both at the same time. If you specify both at the same time, the Java process will be unable to start.

• If you specify both -XX:+UseSerialGC and -XX:+UseG1GC, an error message is output to the standard error output and then the command fails to start. If JNI is used, JNI_CreateJavaVM returns JNI_ERR(-1).
