Java NullPointException - Error while initializing managers

Question

Have a big issue here and need your help. Java seems to be breaking on a number of laptops here at work.

Error while initializing manager: java.lang.NullPointerException, bail out

(Error log on Pastebin)

It was working fine but there were a number of Windows Updates pending. Restarted and Java broke. Has anyone experienced this issue as well? I tried uninstalling the KBs individually and after removing KB2876331, Java worked for a bit. Restarted and Java broke again.

Things I’ve tried:

Uninstall of Java completely from laptop and reinstall, both offline package install and directly from the Java site (Not successful)
Uninstalled Java, reinstalled only 64 bit. (Not successful)
Uninstalled 64 bit then reinstalled 32 bit (Not successful)
Uninstalled Java completely, ran Microsoft fix it utility and reinstalled (Not successful)
Uninstalled Java and used a utility called JavaRa to uninstall remaining components: http://en.kioskea.net/faq/1560-remove-previous-versions-of-java-with-javara (Not succesful)
Ran the install to install java from the same utility JavaRa. It installs Java 6 and that funny enough ends up working!
Tried to update Java 6 from the java console to Java 7 Update 45 and it breaks again (Not successful)
Also tried deleting anything I could for java (folders/registry search) after an uninstall to make sure it was as clean as could be. (Not successful)
Tried Revo Uninstaller to remove Java, didn’t get me any further.

This looks more like a config thing rather than a problem with Java itself, in the log it says:

network: Connecting http://java.com:443/ with proxy=DIRECT javax.net.ssl.SSLException: Unrecognized SSL message, plaintext connection?

This says to me that you are connecting using http (although on port 443) but trying to open an SSL connection. Try https instead of http? Try connecting to that site yourself with a browser and see what actual connection you get.

I just had what looks like the same problem, after upgrading to Java 7 Update 51 (32-bit), in IE10 on 64-bit Windows 8. With logging and tracing on, the last 10 lines of the log are essentially the same as yours, except in my case the .jnlp cache entry was out of date rather than missing. As Tim B spotted, it was trying to connect to http://java.com:443/ with proxy=DIRECT.

The solution here was to turn on IE's proxy - we're behind a MS firewall. Earlier this hasn't been a problem for applets, as Microsoft Firewall Client for ISA Server has handled the traffic.

I've had KB2876331 for over a month, so that's probably not related, but I did get a bunch of other MS updates the other day.

After upgrading to Java 7u79 applets stopped working for me. I needed two things:

Machine restart
Firewall reconfiguration - a new application (jre7\bin\jp2launcher.exe) needed network connections

After many attempts, I managed to solve the problem by full removing the version 8 of Java and install Java 7u80.

Hope this can help you!
