#35 Context cannot be serialized (project NaBL2 on YellowGrass.org)

The constraint solver/scopegraph context cannot be serialized, because it tries to serialize a org.apache.commons.vfs2.provider.local.LocalFile, which is not serializable. This causes the following exception after analyzing a project:
16:31:13 WARN  - Store context file:///Users/gohla/metaborg/repo/progrepr/lang/mod/mod.example/target/analysis/org.metaborg_mod_1.0.0-SNAPSHOT/scopegraph failed.
java.io.IOException: Context file could not be written.
