<p>Hi, when launching the <a data-ipb='nomediaparse' href='
https://wiki.eclipse.org/index.php?title=MemoryAnalyzer/Contributor_Reference#Workspace'>Eclipse MAT RCP</a>, after loading a heapdump, the interactive pie chart on the Overview pane is blank (although a placeholder of the correct size exists). I'm launching from Eclipse Mars 4.5.1 on Linux 64-bit and the matching BIRT plugins are version 4.5.0.v201506092134. Previous versions of Eclipse/BIRT worked fine.</p>
<p> </p>
<p>There were no obvious errors in the console/error log, so I started it with -debug and the following .options file (I just guessed which BIRT logging might be useful):</p>

<p>After a workaround for <a data-ipb='nomediaparse' href='
https://bugs.eclipse.org/bugs/show_bug.cgi?id=482527'>bug #482527</a>, BIRT produced the following output in ...jee-mars/runtime-MAT/.metadata/.plugins/org.eclipse.birt.chart.engine/org.eclipse.birt.chart.engine_2015_11_18_13_06_25_744.log:</p>

<p>Any ideas how to debug further?</p>
