I can confirm that the Sample Viewer crashes the JVM when switching between basemaps. It looks like there's some memory corruption and the crashes appear at random. Just keep clicking in rapid succession to change basemaps and you should get a crash in less than a dozen seconds. The first crash I got was pointing to runtimecore_java.dll+0xFD3B4 (one byte difference with the error that Marcin got, strange). Another one happened at jvm.dll. Also, once the application just closed silently without any explicit crash. I've got these results on the updated version of the Viewer, Windows 7, JVM HotSpot 64-bit build 1.8.0_101-b13, Nvidia Quadro 2000 (369.26 driver).
