Subject: [PATCH] Do not hide root errors on issues resolving line numbers

Currently ASM fails under Java 8. On configuration exceptions Guice
tries too resolve the real root code location which might sometimes 
fail due to an ASM failure.
 
Instead of leading to a totally unrelated $ComputedException which 
completly hides the original cause, this patch simply skips the
line numbers in these case.
