It seems that when the size of requests > 32k， the excetions will appears. But I don't know why this happens and how to solve it.

I am trying to migrate with application startup using the Flyway programatic API, but it seems to fail to load mysql drivers.
I am using gradle everything works fine if I use command line (presummably because I can specify the driver), but I get the following error when application starts up:

We are trying to upgrade JX browser from 6.5.1 to 6.21.
We are having several problems with this.
One is occasional problems initializing the jx browser.

What could be the problem here?
I have a java desktop app using Swing which I rewrote in JavaFX using SceneBuilder.
The Swing app works fine on all users machines (35 Machine). After rewriting the app in JavaFX, on one specific machine the app won't start and gives the below error message.
I couldn't figure out the issue. I appreciate if someone can give any help.
Thank you.

Caused by: java.lang.ClassNotFoundException: com.sun.javafx.css.converters.PaintConverter
at java.base/jdk.internal.loader.BuiltinClassLoader.loadClass(Unknown Source)
at java.base/jdk.internal.loader.ClassLoaders$AppClassLoader.loadClass(Unknown Source)
at java.base/java.lang.ClassLoader.loadClass(Unknown Source)
it looks like the JVM is finding it difficult to locate the com.sun.javafx.css.converters.PaintConverter at runtimewhich causes the ClassNotFoundException Exception error, and which in turn causes the JFoenix library to throw java.lang.NoClassDefFoundError meaning the class was not found on the classpath. This indicates that we were trying to load the class definition, and the class did not exist on the classpath
so first make sure you have the right version of java which is Java 8 to support JFoenix, them make sure The JFoenix library is located in you classpath.
The stack trace, because it prefaces each fully-qualified class name (for example java.lang.ClassLoader) with a module name (e.g. java.base) indicates that the machine is trying to run the application using Java 9.
The CSS converter classes, such as PaintConverter, were promoted from private API, where they were located in Java 8 and earlier, to public API in Java 9. So the class com.sun.javafx.css.converters.PaintConverter no longer exists, and has been replaced by javafx.css.converter.PaintConverter. Hence, when running your application in Java 9, you get a ClassNotFoundException.
The bottom line here is that using any API that is not public, or using third party libraries that do so, is liable to make your application fail if the user updates their JVM. The possible solutions to this problem are:
Avoid using private API, or libraries that use private API
Create and maintain different versions of your code that are for specific JVM versions. In the case of the third-party JFoenix library you are using, there is a separate version for Java 9, so you could create a Java 9 version of the application that uses that version of the library. Note that not only does this create an additional burden on the developer, but it also can potentially create issues for the end user, who will be forced to update the version of your application they use in sync with updating their JVM.
Create a "Self-Contained Application Bundle" for your application. This bundles a specific JVM with your code, so you essentially control the JVM the user uses to run your application. The downsides to this are that you need to create a different bundle for each platform (Windows 32 bit, Windows 64 bit, Mac, Linux) that you want to support, and that the size of the application will increase substantially (to include the JVM).
I would generally recommend the first option when possible, and the third when not.

I am having Java7 sdk in my windows 32 system.
NoSuchFieldError exceptions are thrown "if an application tries to access or modify a specified field of an object, and that object no longer has that field". In this case, it's likely the jar was compiled against one version of java (or other dependency) and you're using a different version that is not compatible.
I'd suggest updating to Java8 since support for Java7 ended as of April 2015. Also, check your version of jetty (since the last call outside the JVM was caused by org.eclipse.jetty.util.DateCache.<init>(DateCache.java:88)) to make sure it's compatible.

I already include all possible kafka jar in run-class.sh but still no luck. Please help!
You are missing jar with the class org.apache.hadoop.conf.Configuration which is not part of the Kafka library. It should be included in hadoop-common-2.5.0. You have to add this jar to the classpath.
