I noticed that 1.6.0_51 exposed missing dependencies in my jnlp in a few cases. The errors were inapparent in previous versions, possibly due to lazy loading. As a concrete example, the jnlp for my local copy of the jfreechart java-web-start demo included the well-known dependencies, jfreechart-1.0.14.jar and jcommon-1.0.17.jar. The javaws GUI noted an exception due to a missing iText-2.1.5.jar. In another case, a missing commons-math-2.2.jar failed silently. Absent detailed knowledge of the vulnerabilities fixed in 1.6.0_51, stricter dependency checking may be a reasonable hypothesis.
