[jira] Created: (AXIS-2310) Incorrect catching of java.lang.Error subclasses
Incorrect catching of java.lang.Error subclasses
------------------------------------------------
Key: AXIS-2310
URL: http://issues.apache.org/jira/browse/AXIS-2310
Project: Apache Axis
Type: Bug
Components: WSDL processing
Versions: 1.3
Environment: Any/all
Reporter: J Ross Nicoll
Axis catches java.lang.Throwable in several places, which is the superclass of Error. This means that errors such as OutOfMemoryError and ThreadDeath are caught. According to the Java virtual machine:
"The class Error and its subclasses are exceptions from which ordinary programs are not ordinarily expected to recover."
In specific, src/org/apache/axis/wsdl/toJava/JavaStubWriter.java line 406:
pw.println(" catch (java.lang.Throwable _t) {");
should be:
pw.println(" catch (java.lang.Exception _e) {");
so that ThreadDeath is not caught, as catching it means that threads never exit properly (see http://java.sun.com/j2se/1.4.2/docs/api/java/lang/ThreadDeath.html).
However, there are likely to be other points where this is an issue, that I haven't found yet, and checking the code would probably be a good idea...
