Hi,
My team were testing if it was viable to include this plugin with our RCP application and we observed the following stack in runtime. The launcher included all plugins available and the DevStyle version: is? 1.11.0.201805291134

The Java version is 1.8_171
The Eclipse is version is Oxygen 2
Both Java and Eclipse are x86.

We noticed that the stack below happened when we tried to change the default theme to the DevStyle one.

Idanez,

The most likely cause for this is the com.genuitec.eclipse.patches plugin is not set to start level 2 and flagged as auto-start. Could you clarify what you mean about making DevStyle the default theme? Are you talking about bypassing the startup sequence and trying to force it directly into DevStyle in your RCP application?

The ability to freely redistribute DevStyle is done with the restriction that its functionality can’t be modified. If you do need to make modifications, you can drop us a note at info@genuitec.com and we can provide you further assistance there.

Cheers.
