Rational Application Developer v7 crashes with the following JVM terminated error message:

This behavior might be caused by the incorrect rendering on a small set of Microsoft Windows computers with bad DirectDraw or Direct3D drivers. Hence, the use of DirectDraw or Direct3D drivers by Java 2D system in Rational Application Developer v7 can cause the crash.

Note: This error is not always caused as the result of DirectDraw or Direct3D drivers.

Consider upgrading to the latest Rational
Application Developer v7.0.x release before carrying out the option of
disabling Direct3D.

In the case of Rational Application
Developer v8.0 or later versions on a Windows 64-bit platform
experiencing this JVM error, consult the technote "Internet Explorer v9 or higher is required if the product was installed using the 64-bit Bit Mode option on a 64-bit system". This addresses the jscript.dll error showing in a javacore.

You can also try clearing the temp folder as described in the followingforum post. The workaround presented is for Lotus Notes, but may also apply in this case.

WORKAROUND:
To turn off the use of Direct3D in Rational Application Developer v7, you can use the following Java parameter option:

-Dsun.java2d.d3d=false

If that does not solve the problems, try removing DirectDraw or Direct3D completely using:

-Dsun.java2d.noddraw=true

Note: You can put this Java parameter option inside the eclipse.ini in the directory <RADv7_install_dir>\SDP70\

Open a service request with IBM support if none of the suggestions above have helped to resolve the problem.
