Using Matlab MCR Runtime version 8.2 (64 bit) on Linux, I get the following error when running a simple code (Note: it is fine under windows):

The class "internal.optim" is undefined. Perhaps Java is not running.

Error in internal.optim.presolve (line 212)

Error in ipqpcommon (line 30)

Error in quadprog (line 468)

Error in qpSolve (line 13)

The class "internal.optim" is undefined. Perhaps Java is not running. Exception in thread "main" java.lang.Exception: The class "internal.optim" is undefined. Perhaps Java is not running.

   at test.MatlabTest.test(MatlabTest.java:142)
   at test.MatlabTest.main(MatlabTest.java:148)

Caused by: com.mathworks.toolbox.javabuilder.MWException: The class "internal.optim" is undefined. Perhaps Java is not running.
