Suddenly Eclipse today has decides to stop working. The last thing I did was close all perspectives and close Eclipse.

When loading eclipse from the command prompt, using: "eclipse.exe -clean" the splash screen loads for a split second then exits.

When I run the command: eclipsec -consoleLog -debug it results in the following output:

Error occurred during initialization of VM
Incompatible minimum and maximum heap sizes specified

Checking Task Manager shows no Java process running and both the CPU and memory usage are very low. I have tried:

• Re-installing Eclipse
• Re-starting my machine

But running eclipsec -consoleLog -debug from the command prompt still results in the issue:
Error occurred during initialization of VM Incompatible minimum and maximum heap sizes specified
