I'm trying to write a custom signature for a java tool called findbugs.  The specific example I'm looking to detect are instances where a static, non-concurrent hashmap is instantiated.  In a multi-threaded environment this causes bad things to happen.  Here is my java source:import java.util.HashMap;import java.util.Map;public class StaticInitializationOfHashMap {    private static Map<String,String> hashMap;    private static void init() throws Exception {        hashMap = new HashMap<String,String>();        for(int x = 0; x < 1000; x++) {            hashMap.put(Key_ + x, Value_ + x);        }    }    public static void main(String[] args) throws Exception {        init();        for(int i = 0; i < hashMap.size(); ++i) {            System.out.println(hashMap.get(Key_ + i));        }    }}Here is my javap -c -v output:Classfile /c:/gitRepos/findbugs/findbugsTestCases/build/classes/StaticInitializationOfHashMap.class  Last modified Oct 27, 2015;

What am I doing wrong?  It appears that the init method was optimized directly into my main method, but I thought that when using Oracle products, that all optimizations were deferred to the JIT and not at compile time?
javap is not displaying an expected method
disassembly;java
Turns out that the problem was me:You need to run the command javap -c -private <className> or else javap defaults to not showing disassembly of private methods.
