Screenshot of the heapdump

Hello,

we are facing OutofMemory exception when running reports on several entries (~4k). From the heap dump we can see that half of the memory is taken by org.eclipse.birt.report.engine.css.dom.CSSValue. Basically we have a about 1M of StyleDeclaration and each instance has an empty array of CSSValue of size 61. 

I have attached a screenshot of the heapdump as the all file is 1.5GB.
