java.lang.Thread.State: WAITING (on object monitor)

I am trying to create weblogic domain using python code which got stuck at filehandler and below is code and stacktrace which is waiting on something can you help to fix it ?

import os
import sys
import wl as myWLST

from java.lang import System,Runtime,Process,String
from java.io import BufferedReader,InputStreamReader,File
from java.util.logging import FileHandler,Logger,SimpleFormatter

from com.oracle.cie.domain.script.jython import WLSTException
from com.oracle.cie.domain.script import ScriptException
from WeblogicConfigXmlParser import XmlParser

#=====================
# Program starts here

if __name__ == "__main__":
    print "in main"
    print len(sys.argv)
    if len(sys.argv) < 2:
                print 'Insufficent arguments'
                System.exit(-1)
    else:
        try:
            print "inside try - JASON"
            print (os.getcwd())
            fileHandler = FileHandler("weblogic.log",1);
            print "inside try 2"
            fileHandler.setFormatter(SimpleFormatter());`

it is stuck at line "fileHandler = FileHandler("weblogic.log",1);",

Stack trace :

Not able to figure why it is stuck at filehandler, it is creating any weblogic.log either and not getting timedout. even i used "-XX:CompileCommand="exclude,java/lang/Object.wait" based on this post object waiting but still no luck.

This is solved after changing the location of the log file from /SHARED to local

OLD :

 fileHandler = FileHandler("/SHARED/weblogic.log",1);
                print "inside try 2"
                fileHandler.setFormatter(SimpleFormatter());`

NEW :

 fileHandler = FileHandler("/home/user/weblogic.log",1);
            print "inside try 2"
            fileHandler.setFormatter(SimpleFormatter());`

filesystem, there is some issue with /shared file system while writing files, which is why it is stuck.
