Just a bit more evidence. The caller of the gerSofaAddr()
public void writeViewsCommons() throws Exception {
// Get indexes for each SofaFS in the CAS
int numViews = cas.getBaseSofaCount();
for (int sofaNum = 1; sofaNum <= numViews; sofaNum++) {
FSIndexRepositoryImpl loopIR = (FSIndexRepositoryImpl)
cas.getBaseCAS().getSofaIndexRepository(sofaNum);
final int sofaAddr = getSofaAddr(sofaNum);
Not an expert of this code, but it smells like another thread is changing a
CAS which is being serialized.
