If using the TCF core framework in an RCP workspace-less environment (-data @none), the TCFSecurityManager fails with an IllegalStateException. There should be fallback besides the plug-in's state directory for the certificates directory, like the users temporary directory. Cannot initialize SSL context java.lang.IllegalStateException: No instance data can be specified. at org.eclipse.core.internal.runtime.DataArea.assertLocationInitialized(DataArea.java:50) at

Created attachment 194203 [details] Possible patch The proposed patch is falling back to the users home directory in case getStateLocation() throws this IllegalStateException. For sure, there might be other more elegant ways to solve the problem. The proposed patch is at least simple and works as far as it effectively falls back to a likely writable location.
I have committed the patch - with some minor changes. Thanks!
