[ https://issues.jboss.org/browse/JBIDE-17894?page=com.atlassian.jira.plugi... ] Pavol Srna commented on JBIDE-17894: ------------------------------------ My steps to reproduce: Use CMD+4 and run * Project new * JPA Setup * JPA Generate Entities From Tables in Generate Entities Wizard fill in: ** JDBC URL: jdbc:h2:tcp://localhost/sakila ** Driver location to the sakila h2 driver ** Select H2 dialect ** username Actual results: * when filling in user name - some validation is taking place (even if verify Database Connection is unchecked) * When changing values in user name field you should be able to see that UI Thread is blocked for a long time - for me on my computer it is more than 10minutes. Expected results: * UI should not be blocked * run validation off UI thread * perform validation on lags during typing and not with every key stroke -- This message was sent by Atlassian JIRA (v6.2.6#6264)
