Please see the java source file and build.xml that follow. Running java
1.4.1_01 under linux as shown by
onofre:2:138 % java -version
java version "1.4.1_01"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.1_01-b01)
Java HotSpot(TM) Client VM (build 1.4.1_01-b01, mixed mode)
ant 1.5.1 as shown by
onofre:2:140 % ant -version
Apache Ant version 1.5.1 compiled on October 2 2002
and junit 3.7.
When I run the small test program (included below) directly
onofre:2:145 % java -classpath junit.jar:. myTest
OK (6 tests)
it runs successfully. Also, when I run it under ant with fork="true", it
runs successfully. When I run it under ant with fork="false", it
generates a
[java] java.lang.NoClassDefFoundError: sun/reflect/ConstructorAccessorImpl
error. The build.xml included belowe runs both the unforked and the
forked cases in that order as seen below.
onofre:2:141 % ant
Buildfile: build.xml
compile:
testNoFork:
[java] java.lang.NoClassDefFoundError: sun/reflect/ConstructorAccessorImpl
testFork:
[java] OK (6 tests)
test:
BUILD SUCCESSFUL
Total time: 2 seconds
I have also found that when I comment out any one of the six test cases,
it runs fine either forked or unforked. Finally, when I switch back to
jdk 1.3, it also runs without error.
I've run out of ideas about what to try and am hoping somebody else
recognizes this or has suggestions.
