Is the GCJ version stable? Faster?
@faq_1051_p
@faq_1052_p
The GCJ version is not as stable as the Java version. When running the regression test with the GCJ version, sometimes the application just stops at what seems to be a random point without error message. Currently, the GCJ version is also slower than when using the Sun VM. However, the startup of the GCJ version is faster than when using a VM.

- What version H2 are you using?
- The first workarounds is: append ;RECOVER=1 to the database URL. Does it work when you do this?
- The second workarounds is: delete the index.db file (it is re-created automatically) and try again. Does it work when you do this?
- The third workarounds is: use the tool org.h2.tools.Recover to create the SQL script file, and then re-create the database using this script. Does it work when you do this?
