从Windows命令行启动时，Apache Derby（JavaDB）静默失败

Question

I'm trying to start database with:

C:\\Program Files\\Java\\jdk1.8.0_60\\db\\bin>NetworkServerControl start

No error messages, prompt returns immediately. And derby.log contains only old messages. As nothing happened. WTF? How can I debug this?

UPD: I have added tracing from https://blogs.oracle.com/wittyman/entry/debug_tracing_in_apache_derby , but derby.log is still empty.
I'm using java.exe from the same JDK (1.8.0 x64)

Answer 1

The solution was to switch to x86 Java version. I've tried several x64 JDKs from 6 to 8, all had failed silently. I think it's Derby bug.

Answer 2

Try running

java -Dderby.debug.true=AssertFailureTrace -jar %DERBY_HOME%\lib\derby.jar server start

It may show some details.
