FULL PRODUCT VERSION : java version "1.6.0_20" Java(TM) SE Runtime Environment (build 1.6.0_20-b02) Java HotSpot(TM) Client VM (build 16.3-b01, mixed mode, sharing) ADDITIONAL OS VERSION INFORMATION : Microsoft Windows XP Version 5.1 (Build 2600.xpsp_sp3_gdr.100427-1636 : Service Pack 3) EXTRA RELEVANT SYSTEM CONFIGURATION : Complete configuration in file reprot.txt attached to this CR. A DESCRIPTION OF THE PROBLEM : SUMMARY: When running an applet that uses with the next generation plugin, intermittent errors occur. The errors appear to be caused by internal Java plugin code. A typical stack trace is as follows (note that getting the stack trace requires increasing Java console trace level to 5): network: Connecting http://localhost:8080/OperationCheck/jsp/log4j.xml with proxy=DIRECT network: Connecting http://localhost:8080/ with proxy=DIRECT com.sun.deploy.net.cookie.CookieUnavailableException: No registered plugin for applet ID 48 at sun.plugin2.main.client.MessagePassingExecutionContext.doCookieOp(Unknown Source) at sun.plugin2.main.client.MessagePassingExecutionContext.getCookie(Unknown Source) at sun.plugin2.main.client.PluginCookieSelector.getCookieFromBrowser(Unknown Source) at com.sun.deploy.net.cookie.DeployCookieSelector.getCookieInfo(Unknown Source) at com.sun.deploy.net.cookie.DeployCookieSelector.get(Unknown Source) at sun.net.www.protocol.http.HttpURLConnection.setCookieHeader(Unknown Source) at sun.net.www.protocol.http.HttpURLConnection.writeRequests(Unknown Source) at sun.net.www.protocol.http.HttpURLConnection.getInputStream(Unknown Source) at java.net.HttpURLConnection.getResponseCode(Unknown Source) at sun.plugin2.applet.Applet2ClassLoader.resourceExists(Unknown Source) at sun.plugin2.applet.Applet2ClassLoader.findResource(Unknown Source) at java.lang.ClassLoader.getResource(Unknown Source) at org.apache.log4j.helpers.Loader.getResource(Loader.java:97) at org.apache.log4j.LogManager.<clinit>(LogManager.java:105) at org.apache.log4j.Logger.getLogger(Logger.java:118) at org.apache.log4j.jmx.HierarchyDynamicMBean.<clinit>(HierarchyDynamicMBean.java:72) at com.toshiba.pf.common.logging.Logger.<clinit>(Logger.java:61) at com.toshiba.pf.entry.engine.EntryImageFactory.<clinit>(EntryImageFactory.java:28) at jp.co.toshiba_sol.imageentry.operationcheck.applet.ISEApplet.init(ISEApplet.java:41) at sun.plugin2.applet.Plugin2Manager$AppletExecutionRunnable.run(Unknown Source) at java.lang.Thread.run(Unknown Source) STEPS TO FOLLOW TO REPRODUCE THE PROBLEM : 1. download apache tomcat and JDK 1.5.0_15: http://ftp.kddilabs.jp/infosystems/apache/tomcat/tomcat-5/v5.5.31/bin/apache-tomcat-5.5.31.zip http://www.oracle.com/technetwork/java/archive-139210.html and configure the following to environment variables: - JAVA_HOME=<JDK1.5.0 path> in setclasspath.bat, e.g.: set JAVA_HOME=C:\jdk1.5.0_15 - CATALINA_HOME=<Tomcat install path> in startup.bat and shutdown.bat, e.g.: set CATALINA_HOME="C:\apache-tomcat-5.5.31" Note: avoid to have pathes which include spaces in their names. 2. extract OperationCheck.zip and put OperationCheck folder into %CATALINA_HOME%\webapps directory. Start Tomcat using startup.bat script. 3. extract JFrameServer.zip and confirm directory is C:\JFrameServer. 4. cd C:\JFrameServer\runtime\1.5\bin and execute following batch file in order. start watcher.bat start tunnelServer.bat start appDispatcher.bat 5. access http://<hostname>:8080/OperationCheck/jsp/index.jsp and confirm button "3��������(JFS+ISE)" is displayed. 6. click "3��������(JFS+ISE)" button continuously EXPECTED VERSUS ACTUAL BEHAVIOR : EXPECTED - Normal communication, cookie sent properly with each request, no exceptions thrown. ACTUAL - Communication fails, cookie missing from request, exception thrown (com.sun.deploy.net.cookie.CookieUnavailableException: No registered plugin for applet ID 3). ERROR MESSAGES/STACK TRACES THAT OCCUR : network: Connecting http://localhost:8080/OperationCheck/jsp/log4j.xml with proxy=DIRECT network: Connecting http://localhost:8080/ with proxy=DIRECT com.sun.deploy.net.cookie.CookieUnavailableException: No registered plugin for applet ID 48 at sun.plugin2.main.client.MessagePassingExecutionContext.doCookieOp(Unknown Source) at sun.plugin2.main.client.MessagePassingExecutionContext.getCookie(Unknown Source) at sun.plugin2.main.client.PluginCookieSelector.getCookieFromBrowser(Unknown Source) at com.sun.deploy.net.cookie.DeployCookieSelector.getCookieInfo(Unknown Source) at com.sun.deploy.net.cookie.DeployCookieSelector.get(Unknown Source) at sun.net.www.protocol.http.HttpURLConnection.setCookieHeader(Unknown Source) at sun.net.www.protocol.http.HttpURLConnection.writeRequests(Unknown Source) at sun.net.www.protocol.http.HttpURLConnection.getInputStream(Unknown Source) at java.net.HttpURLConnection.getResponseCode(Unknown Source) at sun.plugin2.applet.Applet2ClassLoader.resourceExists(Unknown Source) at sun.plugin2.applet.Applet2ClassLoader.findResource(Unknown Source) at java.lang.ClassLoader.getResource(Unknown Source) at org.apache.log4j.helpers.Loader.getResource(Loader.java:97) at org.apache.log4j.LogManager.<clinit>(LogManager.java:105) at org.apache.log4j.Logger.getLogger(Logger.java:118) at org.apache.log4j.jmx.HierarchyDynamicMBean.<clinit>(HierarchyDynamicMBean.java:72) at com.toshiba.pf.common.logging.Logger.<clinit>(Logger.java:61) at com.toshiba.pf.entry.engine.EntryImageFactory.<clinit>(EntryImageFactory.java:28) at jp.co.toshiba_sol.imageentry.operationcheck.applet.ISEApplet.init(ISEApplet.java:41) at sun.plugin2.applet.Plugin2Manager$AppletExecutionRunnable.run(Unknown Source) at java.lang.Thread.run(Unknown Source) REPRODUCIBILITY : This bug can be reproduced often. I've been able to reproduce it with JRE 6u10, 6u20 (customer's actual version), 6u22 (with FVB from CR 6943350 - see below) and 6u23. I've attached the corresponding logs to this CR. Note that for customer this issue can lead to a hang, but customer hasn't been able to produce a test case which generates the hang observed in his production environment. COMPLEMENTARY INFORMATION: This problem can be linked to CR 6943350. We can have sometime the exact same stack given in CR 6943350. Differences are: - the issue is reproducible with JRE 6u10. - the FVB provided in CR 6943350 didn't solve the issue.
