Created attachment 94243 [details] Full output of jstack on deadlocked process I'm running a prerelease of 6.8 Patch 1. Today it proposed to install an update to the JavaFX Composer.

Reassigning to Adam since it is a deadlock in the JavaFX badge resolving/setting.
fixed in http://hg.netbeans.org/javafx/rev/cf37ec81e196
I am forwarding this issue also to Java module. BuildArtifactMapperImpl.FileBuildQueryImpl from Java module is identical and the deadlock is symmetrical so the same fix should work.

Integrated into 'main-golden', will be available in build *201003240200* on http://bits.netbeans.org/dev/nightly/ (upload may still be in progress) Changeset: http://hg.netbeans.org/main/rev/5f6fc17af727 User: Jan Lahoda <jlahoda@netbeans.org> Log: #180854: fixing deadlock.
