The attached test case aot-compiles HelloWorld.java, builds a .db file, and then
"merges" that single .db file into another .db file. (Because it is only
"merging" a single file, and the destination .db does not exist, it is in effect
a copy rather than a merge.) But gcj-dbtool fails with this error message:
java.lang.IllegalAccessException: Table Full: 0
at gnu.gcj.runtime.PersistentByteMap.put(byte[], byte[])
(/usr/lib/libgcj.so.6.0.0)
at
gnu.gcj.runtime.PersistentByteMap.putAll(gnu.gcj.runtime.PersistentByteMap)
(/usr/lib/libgcj.so.6.0.0)
at gnu.java.lang.MainThread.call_main() (/usr/lib/libgcj.so.6.0.0)
at gnu.java.lang.MainThread.run() (/usr/lib/libgcj.so.6.0.0)
This is with gcj-dbtool (GNU libgcj) 4.0.0 20050622 (Red Hat 4.0.0-13)

------- Additional Comments From greenrd at greenrd dot org 2005-06-26 12:39 -------
The problem is that a PersistentByteMap of capacity 1 is created by -m, but when
a PersistentByteMap is created with capacity 1, its capacity method incorrectly
returns 0.
This is because, when it is created, confusingly, the capacity field is set to
(int) (capacity*3/2),which in this case is 1, and the capacity() method then
returns (int) (the capacity field * 2 / 3), which is (int) (2 * 1 / 3) = 0.
The first thing I would do is, we have 3 things (initial capacity, capacity
field, capacity method), all with the same name, but not meaning the same thing,
so I would do some renames to avoid confusion. Then I would fix the actual bug.
Preparing a patch.
