Out Of Memory Error When Opening Large Documents

Problem

I am trying to open a file larger than 100 MB in Oxygen JSON Editor, but it runs out of memory (OutOfMemoryError).

Solution

You should make sure that the value of the Optimize loading in the Text edit mode for files over option is less than the size of your document. This will enable the optimized support for large documents. If that fails and you still get an Out Of Memory error you should increase the memory available to Oxygen JSON Editor.
