I have a not big embeded database and when I want to script it using
org.h2.tools.Script class I get an Out of memory exception. The solution is
ofcourse to use more java heap space, by running class with -Xmx1024m
argument.
Exception stack tells me one thing:
Exception in thread "main" java.lang.OutOfMemoryError: Java heap space
at java.util.Arrays.copyOf(Unknown Source)
at java.lang.AbstractStringBuilder.expandCapacity(Unknown Source)
at java.lang.AbstractStringBuilder.append(Unknown Source)
at java.lang.StringBuffer.append(Unknown Source)

at org.h2.tools.Script.main(Script.java:57)
H2 developers use StringBuffer to append new queries, I think the better
solution would be write to FileOutputStream - the out of memory problem will
not exist in this case.
