Looks like a problem with the incomplete implementation of NIO File locking in kaffe. > With SableVM I get > > $ sablevm -c .:/usr/share/java/hsqldb.jar Test > [...] > ERROR: > java.sql.SQLException: General error: java.lang.ExceptionInInitializerError > at org.hsqldb.jdbc.jdbcUtil.sqlException (jdbcUtil.java:67) > at org.hsqldb.jdbc.jdbcConnection.jdbcConnection (jdbcConnection.java:2427) > at org.hsqldb.jdbcDriver.getConnection (jdbcDriver.java:188) > at org.hsqldb.jdbcDriver.connect (jdbcDriver.java:166) > at java.sql.DriverManager.getConnection (DriverManager.java:164) > at java.sql.DriverManager.getConnection (DriverManager.java:188) > at Test.main (Test.java:12) > at java.lang.VirtualMachine.invokeMain (VirtualMachine.java) > at java.lang.VirtualMachine.main (VirtualMachine.java:108) Most probably same here. I dont looked into hsqldb source code to check but can ypu extract a testcase from it that reproduces the same exception with kaffe ? I guess its some bug/missing feature with NIO file locking.
