I am talking about "Find/Replace" dialog (Ctrl+F).

It seems to support "variable length lookbehind" regex which doesn't seem to be supported in Java. Or, is it really using Java?

I need to know exact version if possible.

Search uses this which definitely creates a java.util.regex.Pattern.

org.eclipse.search.internal.core.text.PatternConstructor.createPattern(String, boolean, boolean, boolean, boolean)

Also in org.eclipse.jface.text.FindReplaceDocumentAdapter.findReplace(FindReplaceOperationCode, int, String, String, boolean, boolean, boolean, boolean) is does a Pattern.compile so it is just using what's provided by the JDK.
