Exception while running JavaFX 8 application with Ant

I'm trying to compile and run a JavaFX project using ant. Compilation using ant is OK, however, when I try to use ant run and launch the application, i get this error:

From what I've found online, this error occurs, when the project's .fxml file can't be found.
This only occurs when I try to use ant to run the program. When I run it using intelliJ IDE everything works just fine. I've even reproduced this error when running the program using IDE by giving it wrong .fxml resource url. So I guess that ant just can't find the fxml file, hovewer I am lost in this regard and dont know how to make my build.xml find the .fxml.
This is my build.xml file:
<project name="ija-app" basedir=".">

Thanks for any tips on how to get it running.

Handle java.lang.NegativeArraySizeException in Intellij IDE on ant input

<target name="readme" description="Create readme.txt for Build">
<echo>Creating readme.txt file </echo>
<input
message="Enter text for Readme.txt:"
addproperty="README_TXT"
defaultvalue="This is for file input: ${ant.project.name}"
/>
<echo>Text is: ${README_TXT} </echo>
</target>
When executing this,
When entered a simple sort string This is test line it is working fine
When entered a long string like a,jsha,mskahskakshkahskhakshakskaksdhksdfsfd.,df,d'fdkf;dfdljflkdhfdhkfdkhfkdhfkdkfdkf
it's throwing Exception:

I am using NetBeans 8.1 with only JDK 8 (both 32bit). I am also using Windows 8. I have performed a clean on the build-impl.xml from within NetBeans and I am still seeing this issue. Is it related to Ant somehow? I don't even really know what Ant is or does.
Here is the output for line 1039:

I have had the same problem and I have created a new glassfihs server and then it has worked...

ClassCastException in ant schemagen task using jaxb-ri-2.2.7

I'm trying to use the schemagen ant task from JAXB-RI 2.2.7, but I keep getting "BUILD FAILED .... Error starting ap" on the schemagen task in build.xml. The relevant stanzas are as follows:
<taskdef name="schemagen" classname="com.sun.tools.jxc.SchemaGenTask">
<classpath refid="compile.classpath"/>
</taskdef>
<target name="schemas" description="Compile all Java source files">
<mkdir dir="${schemas.dir}" />
<schemagen destdir="${schemas.dir}">
<src path="${src.dir}"/>
<classpath refid="compile.classpath" />
</schemagen>
</target>
With -verbose, I get the stack trace below. I've tried googling for the details of the ClassCastException but not found anything. Any suggestions?
Thanks, Adam

Same problem here. From the stack trace I would say it's some error in JAXB annotation, but while xjc tries to handle that exception it fails with another one and there's no way of knowing in which class and property the problem is.
