SpreadsheetView Error - controlsfx

I used spreadsheet view of controlsfx 8.0.6U25 with earlier jdk for my work and it worked good. Recently I updated to JDK 8U40 and controlsfx 8.20.8. Sadly, the spreadsheet view won't load. I get error in my IDE anytime I run the same project. Please, has anyone faced the same problem? What is the solution? Thank you.
Please find the error I get below. I made no changes before the update.

Exception running application myStudentAssessNew.StudentAsessment

Well, the solution rather looks simple. Since controlsfx project has not yet been updated to meet JDK 8u40 and above as at now, I just reinstalled the previous jdk (JDK 8u25) and I am okay now.

Getting Rita.WordNet to work

According to Rita Homepage you just have to download Rita.jar and
WordNet-3.1 and add both to thebuild path of your java project.
I did it like that and everytime i try to use it:
RiWordNet wordNet = new RiWordNet(Test.class.getResource("/WordNet-3.1").getPath());
I get:

The data files are no longer supplied as part of the installation. You need to download the WordNet version for your platform and then pass it to the constructor, as documented here.

If I run this applet from eclipse, it runs fine. I suspect there may be issue with jre version or accessing rt.jar in jre runtime. This is not code related issue for sure as everything was working until my system got restarted (it reboots per company policy on weekend). Therefore, any setting may have been changed.
Browser used: Chrome
latest version of jre on machine: jre7
code compiled using: jre6
Kindly respond as I have been facing this issue for long time now.
UPDATE:
Just to add, I get this error when I try to read xml file to Java class using annotaions in thoughtworks xstream lib

sun.misc is a vendor specific class which should not be used in portable Java code.
Either make the code portable or switch the browser plugin to the Oracle JVM.

Looks my jre installation got corrupt. I reinstalled it and it fixed the issue.

NPE with logging while launching webstart on jre7 update 40

My application was running fine until I upgraded my jre to 7u40. When my application is initializing, it's doing Logger.getLogger("ClassName"), and I'm getting the following exception.

The exception is coming from this line:
private static Logger logger = Logger.getLogger(Applet.class.getName());
Could it be because of any sideeffects with fix http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=8017174 ?
A workaround is to open the java control center and enable logging. This is a concern since by default "Enable Logging" is unchecked. If I select "Enable Logging", the application starts fine.

This problem seems to be fixed in java7 update 45.

Try to package java.util.logging.* with your app in a JAR, and make sure it's on the classpath. That way it is always available. Also, what does your logging.properties look like?

Install4j is bypassing the custom installation steps

We have an application packed with install4j.
The initial step is to choose between typical and custom installations.
The custom installation is usually bringing up the option to choose the localsettings folder, the appdata folder and in the next step, the installation folder (default: Program Files).
For some reason, in a specific environment, when checking neither of the options, the installation proceeds without asking for the desired folder paths.
An error file was created as well:

Could you please let me know, what could be the reason for this behavior?

The class that is not found is for a script in your install4j project. This can only happen if there is an inconsistency in your installation directory, i.e. if .install4j/user.jar and .install4j/i4jparams.conf are not from the same installer.
