Only for that reason, in jOOQ 3.7, we've letDSLContextextendAutoCloseable:#4479, which is possible starting from Java 8,as theAutoCloseablecontract made closing it optional. Unfortunately, this has lead to confusion numerous times, especially when people turn on static code analysis tools that che...
What could be kind of surprise even for some experienced Java programmers, the java.util.Stream interface extends java.lang.AutoCloseable. This (in theory) puts it on par with files, DB connections, and other resources requiring manual closing. Should we
