-Dsun.awt.keepWorkingSetOnMinimize

The -Dsun.awt.keepWorkingSetOnMinimize=true system property stops the JVM trimming an application when it is minimized.

-Dsun.awt.keepWorkingSetOnMinimize=true

When a Java™ application using the Abstract Windowing Toolkit (AWT) is minimized, the default behavior is to "trim" the "working set". The working set is the application memory stored in RAM. Trimming means that the working set is marked as being available for swapping out if the memory is required by another application. The advantage of trimming is that memory is available for other applications. The disadvantage is that a "trimmed" application might experience a delay as the working set memory is brought back into RAM.

The default behavior is to trim an application when it is minimized.
