---------------------------------
Summary: UIMA Ruta SeedLexer throws Error instead of exception
Key: UIMA-6131
URL: https://issues.apache.org/jira/browse/UIMA-6131
Project: UIMA
Issue Type: Improvement
Components: Ruta
Reporter: Mario Juric
The SeedLexer and possibly other related classes used by Ruta throw
java.lang.Error instead of java.lang.Exception. This is usually only thrown by
the JVM when it’s really impossible to continue the process, e.g. out of
memory, linkage errors or fatal VM failures, and it therefore not meant to be
caught under normal circumstances, so most runtime environment don't capture
these. This can therefore cause the whole process to fail instead of just the
document being processed.
It would therefore be preferable if these components throw a type of
java.lang.Exception instead, so that the process can proceed with the next
document without the need to hook into the runtime core and catch
java.lang.Error. The errors are also not subclassed, so it's awkward to
distinguish them by checking for the message string itself.
