I am also facing the same issue: Caused by: org.h2.jdbc.JdbcSQLException: Database may be already in use: null. Possible solutions: close all other connection(s); use the server mode [90020-192]. It seems we have to connect to H2 server in TCP mode, else H2 is still in use. This as per the below stack overflow link, it would be good to know from experts on how to resolve this issue. http://stackoverflow.com/questions/8158969/h2-database-error-database-may-be-already-in-use-locked-by-another-process

Maybe you have multiple instances of the Application running ? Go to "View->Tool Windows->Run" and stop/close the running apps before staring a new one.

yes this is correct answer - stop application and restart from that window - if you just run again, then the second run will not work
