Hi,
we only test against Sun/OpenJDK 1.5, 1.6, 1.7 and 1.8. Currently we
cannot consider other JREs vendors.
The problem is with the "runtime access", the strategy to connect
instrumented classes with the JaCoCo runtime. We have several
implementations, all with different pros and cons. Unfortunatelly one of
them (which works best with the JRE above) is hardcoded on the JaCoCo
agent. Future versions of JaCoCo might have a option to switch between
different runtimes.
Alternatively you can use "offline instrumentation" which dies not need
"runtime access" as the instrumented classes get a direct dependency on
JaCoCo: http://www.eclemma.org/jacoco/trunk/doc/offline.html
Best regards,

I tried to start application server, but threw below exception. I
tested with IBM JDK 1.6, everything is fine.
