I'm using H2 1.3.172 on a Windows machine with the following connection
string:
jdbc:h2:tcp://localhost/dev/*****;LOG=0;UNDO_LOG=0;DB_CLOSE_ON_EXIT=TRUE;IGNORECASE=TRUE;OPTIMIZE_REUSE_RESULTS=0;QUERY_TIMEOUT=180000;MAX_OPERATION_MEMORY=0;MAX_MEMORY_ROWS=30000;COMPRESS_LOB=NO;LOCK_MODE=0;MULTI_THREADED=0;CACHE_SIZE=1048576;TRACE_LEVEL_FILE=2;
I receive the following exception when trying to connect to an existing
database:
General error: "java.lang.NullPointerException"
Scenario:
- I have a highly complex process around the H2 database.
- It all works fine with no issues.
- When the IIS reaches an idle session timeout an attempt to close any
open connections is made.
-
Failure as shown in the trace log (last few lines):

I assume the issue with me closing the connection, but I could really use
some guidance as to the exact cause and workaround.
Many thanks,
