Error including line segments in EJsS

Hi there!
I am struggling to see what is wrong with the code attached. The problem is with the last line segment "segment2" that has sizeX and sizeY related to variables h and f. When I make the sizes constants then the problem disappears. Also removing some of the other segments in the drawingPanel makes the problem go away.
What is the problem, exactly? I don't know what it is supposed to do, but it seems to me it does what is expected. I mean that, if I change the size of the object using the second slider, the arrow honours the change...
Sorry, I didn't explain very well at all. On my machine, if I try to run the code in a browser then I get the following errors:
Exception in thread "AWT-EventQueue-0" java.lang.StackOverflowError at org.mozilla.javascript.NativeArray.setLength(NativeArray.java:640) at org.mozilla.javascript.NativeArray.setInstanceIdValue(NativeArray.java:129) at org.mozilla.javascript.IdScriptableObject.put(IdScriptableObject.java:362) at org.mozilla.javascript.NativeArray.put(NativeArray.java:387) at org.mozilla.javascript.ScriptableObject.putProperty(ScriptableObject.java:2347) at org.mozilla.javascript.ScriptRuntime.setObjectProp(ScriptRuntime.java:1598) at org.mozilla.javascript.NativeArray.setLengthProperty(NativeArray.java:712) at org.mozilla.javascript.NativeArray.js_slice(NativeArray.java:1432) at org.mozilla.javascript.NativeArray.execIdCall(NativeArray.java:305) at org.mozilla.javascript.IdFunctionObject.call(IdFunctionObject.java:97) at org.mozilla.javascript.ScriptRuntime.applyOrCall(ScriptRuntime.java:2430) at org.mozilla.javascript.BaseFunction.execIdCall(BaseFunction.java:269) at org.mozilla.javascript.IdFunctionObject.call(IdFunctionObject.java:97) at org.mozilla.javascript.optimizer.OptRuntime.call2(OptRuntime.java:42) at org.mozilla.javascript.gen.JSUGLIFY_19._c_slice_106(JSUGLIFY:1325) at org.mozilla.javascript.gen.JSUGLIFY_19.call(JSUGLIFY) at org.mozilla.javascript.optimizer.OptRuntime.callName(OptRuntime.java:63) at org.mozilla.javascript.gen.JSUGLIFY_19._c_anonymous_149(JSUGLIFY:1506) at org.mozilla.javascript.gen.JSUGLIFY_19.call(JSUGLIFY) at org.mozilla.javascript.ScriptRuntime.applyOrCall(ScriptRuntime.java:2430) at org.mozilla.javascript.BaseFunction.execIdCall(BaseFunction.java:269) at org.mozilla.javascript.IdFunctionObject.call(IdFunctionObject.java:97) at org.mozilla.javascript.optimizer.OptRuntime.call2(OptRuntime.java:42) at org.mozilla.javascript.gen.JSUGLIFY_19._c_walk_154(JSUGLIFY:1537) at org.mozilla.javascript.gen.JSUGLIFY_19.call(JSUGLIFY)
...... and more .....
This also happens if I try to package the simulation.
If I start to remove items from the drawingPanel then the problem mysteriously goes away.
