EXTRA RELEVANT SYSTEM CONFIGURATION :
It is reported when jar files are downloaded from Server using applets

A DESCRIPTION OF THE PROBLEM :
While accessing our application it opens anapplet window and tries to download the jar file from the server. It was able to download the jar file successfully on 1.7.0_67 but when we upgraded the java to 1.7.0_72-b14 it stopped working and was not able to download the jar file.

When we check the java console with trace level enabled we found that our proxy.pac file content was dumped on the console with "java.net.SocketException: Unknown proxy type : HTTP" error message.

REGRESSION.  Last worked in version 7u67

1) Access a web application which tries to invoke an applet to download the jar file from server
2) This jar file is downloaded via common proxy.pac file
3) Applet window will hang and will not move further and jar file is not downloaded
4) Check the java console in trace level for the error information

EXPECTED VERSUS ACTUAL BEHAVIOR :

Comments

According to the description: the problem was caused by incorrect work of isResolvable(host) function. The function invokes dnsResolve(host) during execution. It is most likely this known and already fixed issue. I believe this is an instance of JDK-8061643 or JDK-8061648. Both were fixed and integrated into 7u79 and 7u80 which are available for downloading at Oracle site. I recommend re-test the problem on 7u79 or 7u80. I am closing this as dupe of JDK-8061648 since it is based on JDK-8061643. If the problem is still present, please re-open.

Response from the submitter: --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- Unfortunately the URL can only be accessed from the intranet and not from public domain. As additional information I have attached the example proxy.pac file which is used in this case. As per my observation entire content after the method isResolvable(host) (see below) is dumped on the java console and the Socket HTTP error was thrown. Please let me know if you need any further information, I am happy to provide. } else if (!isResolvable(host)) { return "PROXY 12.139.14.15:8080" } else if (isInNet(host, "12.134.12.15", "255.255.254.0") || (isInNet(host, "12.114.75.4", "255.255.255.255")) || (isInNet(host, "12.114.75.5", "255.255.255.255")) || (isInNet(host, "12.114.75.6", "255.255.255.255")) || (isInNet(host, "12.114.75.7", "255.255.255.255")) || (isInNet(host, "12.114.75.8", "255.255.255.192"))) { return "DIRECT" // USE F5 LOADBALANCER VIP } else { return "PROXY 12.139.14.15:8080" } } -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
