[Bug java/20302] New: Problem with sub classes with contructors with exceptions

[steve at netfuel dot com]

GCJ does not handle compilation of sub classes with out explicitly defined
constructors to override the super class constructors when the constructors
throw exceptions.

[steve@helios steve]$ gcj Test.java -c Test.o
Test.java: In class 'Test$1':
Test.java: In constructor '(Test,java.io.ByteArrayInputStream)':
Test.java:9: error: Exception 'java.io.IOException' must be caught, or it must

I think this is a dup of another bug, but I am too lazy to find the bug right now.

I have looked for this bug and did not see one.

15501 is similar but is not the same problem or is a subset of the problems
defined in my report.  As my bug also affects any Extends with Exceptions
defined in the super class constructor.

The work around is to add the overrideing constructors and call super(..)

Note that Test2.java actually is invalid code.
Unlike anonymous constructors, implicit constructors are
not given any special treatment when it comes to 'throws'
clauses.

Test.java is valid code and should not be rejected.

All gcj front end bugs have been fixed by the gcj-eclipse branch merge.
I'm mass-closing the affected PRs.
If you believe one of these was closed in error, please reopen it
with a note explaining why.
Thanks.
