Method o.n.m.java.source.ant.ProjectRunnerImpl.execute(), which leads to
ClassPath.getRoots() and FileUtil.addFileChangeListener(), is called in EDT.

Reassigning to java/Source. Please evaluate it. Thank you.

Comment 3 Svata Dedic 2014-08-08 20:50:23 UTC

Project action's decision is to execute the JavaRunner in EDT. I'm not sure if it is avoidable, please evaluate.

Comment 4 Tomas Stupka 2015-09-21 08:56:51 UTC

closing for now.
