runInTerminal reverse-request missing cwd key

According to the DAP specification, the cwd key in the runInTerminal request is mandatory.

https://microsoft.github.io/debug-adapter-protocol/specification#Reverse_Requests_RunInTerminal

however, the java debug server sends the request without this key:

2018-12-20 00:03:04,861 - DEBUG - Message received: {'command': 'runInTerminal', 'arguments': {'kind': 'integrated', 'title': 'Java Debug Console', 'args': ['/Library/Java/JavaVirtualMachines/jdk1.8.0_162.jdk/Contents/Home/jre/bin/java', '-agentlib:jdwp=transport=dt_socket,server=n,suspend=y,address=localhost:53159', '-Dfile.encoding=UTF-8', '-cp', '/Users/ben/.vim/bundle/vimspector/support/test/java/test_project/target/classes', 'com.vimspector.test.TestApplication', 'hello', 'world!']}, 'seq': 2, 'type': 'request'}

of course, clients could work around this, but it would be nice for the server to include the required parameter.

Start by locating the Java debug server code that constructs the DAP runInTerminal reverse request, then compare its arguments with the linked DAP specification. The work is done when the request includes the mandatory cwd key and the relevant request behavior is covered by the project's tests.
