Error of loading java class from another module in time of debugging

[ddementieva]

Use case

Open multi-module project in Eclipse Che, for example [https://github.com/codenvy/cdec|CDEC project].

Set breakpoint into java class which uses class from another module, for example, in class [ConfigCommand.java https://github.com/codenvy/cdec/blob/master/installation-manager-cli-bundle/src/main/java/com/codenvy/im/cli/command/ConfigCommand.java#L58] of module installation-manager-cli-bundle.

Run project in debug mode.

Connect to remote debug session of project from Che.

Step into method of class of another module, for example, AbstractArtifact.createArtifact()

of module installation-manager-core.

Actual wrong result
IDE opens tab with title ArtifactFactory and error message instead of content:
{noformat}
An error occurred while loading the file.
