java.lang.NoClassDefFoundError: com/oracle/truffle/api/TruffleRuntimeAccess while running with self built Graal JDK

[Renze Torensma]

Hi,

After following the instructions on the wiki page for building a Graal VM (https://wiki.openjdk.java.net/display/Graal/Instructions <https://wiki.openjdk.java.net/display/Graal/Instructions>) and setting up Eclipse (https://wiki.openjdk.java.net/display/Graal/Eclipse <https://wiki.openjdk.java.net/display/Graal/Eclipse>) I managed to get SL running on a normal JDK (1.8.0_60) but when I select the Graal JDK I built (same version, 1.8.0_60) as alternative JRE I get a java.lang.InternalError:

The workspace reports 0 problems, even no warnings about deprecated code which seems a little odd to me. I’m not sure what I’m doing wrong, and I don’t really know how to use the provided Truffle and Graal builds on http://lafo.ssw.uni-linz.ac.at/builds <http://lafo.ssw.uni-linz.ac.at/builds> to check if that would fix the problem. I tested on Eclipse Luna and Eclipse Mars and with JDK 1.8.0_60 and 1.8.0_66 but the error happens in all cases.

Thanks,
Renze
