I have a JTabbedPane in a JDialog box that uses GridBagLayout on all the JPanels contained within the pane. On the first panel displayed there is a JTextArea (descTxt) that is ready to input a film description in. When you input a large amount of text into the JTextArea it seems fine up until you click anywhere on the panel that isn't a component (empty grey space) and then all the text fields and text panes shrink to what seems to be size 0.
Here is some example text to paste in and to test:
During a manned mission to Mars, Astronaut Mark Watney is presumed dead after a fierce storm and left behind by his crew. But Watney has survived and finds himself stranded and alone on the hostile planet. With only meager supplies, he must draw upon his ingenuity, wit and spirit to subsist and find a way to signal to Earth that he is alive.
Here is a runnable example of my code:

Please help. This one is very confusing and I can't seem to find a solution anywhere.
So, the problem seems to a combination of setResizable(false) and ScrollPaneConstants.VERTICAL_SCROLLBAR_AS_NEEDED (alright, I just hate unresizable windows).
What's happen is, when you fill the JTextArea, it's "adding" the JScrollPane into an already "packed" window, so there component's size has changed, then when the container is revalidated, there is no longer enough space left to pack all the fields into at their preferred size, so they are been sized to their minimum size instead, which is typically 0x0 or near enough.
There are a few things you can do to help things along. You could use GridBagConstraints#fill and use GridBagConstraints.HORIZONTAL for the text fields and GridBagConstraints.BOTH for the text area's, what this will do is allow the fields to "fill" and occupy the available space of the column/row regardless of when the cell space is smaller than the component's preferred size.
You might also find GridBagConstraints#weightx/y to 1 can help.
And if you're having real trouble, you could simply use ScrollPaneConstants.VERTICAL_SCROLLBAR_ALWAYS in the JScrollPane, which while not pretty, will add in the JScrollBar size into the JScrollPane when the window is packed
Updated
So, basically, I ended up using a combination of fill and weightx/y for the JScrollPane's and JTextAreas
g1.fill = GridBagConstraints.BOTH;
g1.weightx = 1;
g1.weighty = 1;
adminPanel1.add(descTxtPane, g1);
g1.fill = GridBagConstraints.NONE;
g1.weightx = 0;
g1.weighty = 0;
For the JTextFields I just used fill which seems to have stabilised things...
g1.fill = GridBagConstraints.HORIZONTAL;
adminPanel1.add(idTxt, g1);
g1.fill = GridBagConstraints.NONE;
Which resulted in something like...
