Problems with Serializable-String[] in 2.96

Mon Sep 16 15:07:00 GMT 2002

I built version 3.2 and have a similar problem. After
building and changing my path so it searches 
/usr/local/bin first it looks like version 3.2 is
used, i.e executing:
gcj -dumpversion 
results in 
3.2
I followed the installation instructions @
http://gcc.gnu.org/java/build-snapshot.html
I get the following when compiling the program below:
[root@PetesRedHat java]# gcj --main=example.TestSer -o
Test TestSer.class
example/TestSer.java: In class `example.TestSer':
example/TestSer.java: In method
`example.TestSer.main(java.lang.String[])':
example/TestSer.java:9: verification error at PC=52
example/TestSer.java:9: invalid argument type
example/TestSer.java:9: expected type
'java.io.Serializable' but stack
contains 'java.lang.String[]'
[root@PetesRedHat java]#
The following is source I am able to build with Sun's
jdk 1.1.8, but fails with gcj 3.2
package example;
import java.io.Serializable;
public class TestSer {
 public static void main (String[] args) {
 TestSer testSer = new TestSer();
 String[] values = {"one", "two","three",
"four","five", "six","seven"};
 testSer.printArgs((Serializable) values);
 }
 public void printArgs(Serializable values) {
 String[] strings = (String[]) values;
 for (int i=0; i<strings.length; i++) {
 System.out.println("value[" + i + "]: 
" + strings[i]);
 }
 }
}
Thanks for the help,
Pete
