java - Illegal access: this web application instance has been stopped already -

hi have class has init-method defined in xml

<bean id="appstarter" class="com.myapp.myclass" init-method="init" destroy-method="destroy"/>

myclass:

public class myclass{      private thread t;      public void init() {               t = new thread() {                  @override                 public void run() {                     while (true)                         try {                             dostuff();                             thread.sleep(1000);                         } catch (exception e) {                             e.printstacktrace();                         }                 }              };             t.start();         }  public void destroy() {         t.interrupt();     }  }

when app starts threads runs fine, , works fine , after sometime got following exception

info: illegal access: web application instance has been stopped already.  not load com.sun.mail.imap.imapstore.  eventual following stack trace caused error thrown debugging purposes attempt terminate thread caused illegal access, , has no functional impact. java.lang.illegalstateexception     @ org.apache.catalina.loader.webappclassloader.loadclass(webappclassloader.java:1273)     @ org.apache.catalina.loader.webappclassloader.loadclass(webappclassloader.java:1233)     @ javax.mail.session.getservice(session.java:755)     @ javax.mail.session.getstore(session.java:569)     @ javax.mail.session.getstore(session.java:531)     @ javax.mail.session.getstore(session.java:510)

in dostuff method:

public void dostuff(){  session sessioned = session.getdefaultinstance(system.getproperties(),                 null);         store store = sessioned.getstore("imap");         store.connect(hostname, username, password); . . .  }

i don't know why, ideas ?

problem solved after restarting tomcat , apache, tomcat caching older version of app.

i want make logharitmic fit. keep getting runtime error: optimal parameters not found: number of calls function has reached maxfev = 1000 i use following script. can tell me go wrong? use spyder still beginner. import math import matplotlib mpl scipy.optimize import curve_fit import numpy np #data f1=[735.0,696.0,690.0,683.0,680.0,678.0,679.0,675.0,671.0,669.0,668.0,664.0,664.0] t1=[1,90000.0,178200.0,421200.0,505800.0,592200.0,768600.0,1036800.0,1371600.0,1630800.0,1715400.0,2345400.0,2409012.0] f1n=np.array(f1) t1n=np.array(t1) plt.plot(t1,f1,'ro',label="original data") # curvefit def func(t,a,b): return a+b*np.log(t) t=np.linspace(0,3600*24*28,13) popt, pcov = curve_fit(func, t, f1n, maxfev=1000) plt.plot(t, func(t, *popt), label="fitted curve") plt.legend(loc='upper left') plt.show() your original data t1 , f1 . therefore curve_fit should given t1 second argument, not t . popt, pcov = curve_fit(func,
