Using a declared type as a field for another declared type causes NoClassDefFoundError causes the following Exception:

Exception in thread "main" java.lang.NoClassDefFoundError: com/sample/Cap

at org.mvel2.optimizers.dynamic.DynamicGetAccessor.getValue(DynamicGetAccessor.java:73)

at org.mvel2.compiler.ExecutableAccessor.getValue(ExecutableAccessor.java:42)
at org.mvel2.MVEL.executeExpression(MVEL.java:952)

when MVEL optimization, trying to jit the accessor to that field, kicks in.
