Found an error whenever a source is focused on (assuming refreshing Outline) and it contains an 'out' in the parameters for methods.
This is the message I get:

An error has occurred. See error log for more details.
java.util.EmptyStackException

When I comment out the methods, the error doesn't appear.
Also, the Outline view is empty for the source.

Can you please post some source code and the error log? I'm not able to reproduce it.

Eclipse newbie question:
Where is the error log at? I couldn't find it.

the code that produced the error:
Edit: This code was translated from a C# project I was working on. It works exactly as it should when compiled:

Vector2D ConvertToVector2D(out bool InRegion, out double ZDepth) {
Vector3D vector = this + pWorldSize; // 3D Vector to convert
Vector2D vectorResult = new Vector2D(); // 2D Vector to store result
Vector3D cameraPosition = pC + pWorldSize; // new Vector3D(pWorldSize.X, pWorldSize.Y, 0); // Camera Position (default = 0, 0, 50)
Vector3D translation = new Vector3D(); // Temporary vector to store translation for projection
Vector3D theta = new Vector3D(pTheta.X * (PI / 180),
pTheta.Y * (PI / 180), pTheta.Z * (PI / 180)); // Camera angle / Translate degress to radians
Vector3D viewScreen = pE; // +new Vector3D(0, 0, pWorldSize.Z); // Projection screen location

double MinClip = pWorldSize.Z * .25;
double MaxClip = pWorldSize.Z * 10;

// Extracted from inline algorithms for debugging purposes
double sinX = sin(theta.X);
double cosX = cos(theta.X);
double sinY = sin(theta.Y);
double cosY = cos(theta.Y);
double sinZ = sin(theta.Z);
double cosZ = cos(theta.Z);

// Translation of coordinates: taken from http://en.wikipedia.org/wiki/3D_projection
translation.X = cosY * (sinZ * (vector.Y - cameraPosition.Y) + cosZ * (vector.X - cameraPosition.X)) - sinY * (vector.Z - cameraPosition.Z);
translation.Y = sinX * (cosY * (vector.Z - cameraPosition.Z) + sinY * (sinZ * (vector.Y - cameraPosition.Y) + cosZ * (vector.X - cameraPosition.X))) + cosX * (cosZ * (vector.Y - cameraPosition.Y) - sinZ * (vector.X - cameraPosition.X));
translation.Z = cosX * (cosY * (vector.Z - cameraPosition.Z) + sinY * (sinZ * (vector.Y - cameraPosition.Y) + cosZ * (vector.X - cameraPosition.X))) - sinX * (cosZ * (vector.Y - cameraPosition.Y) - sinZ * (vector.X - cameraPosition.X));

ZDepth = pC.Distance(translation);
// Project translated coordinates to 2D screen
// Prevent div by zero
double Zprojection;
if(translation.Z == 0) {
Zprojection = 0;
} else {
Zprojection = (viewScreen.Z / translation.Z);
}
if(ZDepth > MaxClip | ZDepth < MinClip) {
InRegion = false;
} else {
InRegion = true;
}

vectorResult.X = (translation.X - viewScreen.X) * Zprojection;
vectorResult.Y = (translation.Y - viewScreen.Y) * Zprojection;

pFOV = (2 * atan(1 / viewScreen.Z)) * (180 / PI);
return vectorResult;
}

Copied that code to a source file, no problem at all. Does it happen always?

You can see the error log in Windows -> Show View -> Other -> PDE Runtime -> Error Log

[Rob10e]

Oddly enough, I don't have that PDE runtime as an option.
It doesn't happen if I have that code commented out. Any other time, yes it always happens.

I did get this from error report:
