org.netbeans.modules.editor.lib2.document.ReadWriteUtils.read() can be improved to use less memory especially for large files.

Comment 9 Miloslav Metelka 2015-09-07 15:24:04 UTC 
Alghough the editor document implementation is capable of repetitive insertions upon document read all the document listeners are triggered upon each insertion (including e.g. lexer's relexing etc.). So ReadWriteUtils.read() attempts to fully read the stream so that just a single insert is made which should be the most efficient approach.

As the ReadWriteUtils.read() can perform several memory allocations it's often shown in OOMEs but it does not itself leak the memory. All the current editor's memory leaks should be resolved in terms of issue #239360 so making this issue a dup of it.
