Can't find javac's classes unless they are on sysclasspath

Name: ouC59006 Date: 06/18/98



When the compiler is called from some java program, it can't find some classes
which are actually on the CLASSPATH variable. My understanding is that the compiler
now (starting from JDK-1.2beta4-H) is being loaded by the same class loader as the
user aplication. Then, it should find all the classes which are on the user
CLASSPATH.

Example a.java below exhibits the problem. Note that if one sets that same
class path into -Xsysclasspath java option, it runs the program successfully.
For the first time this behaviour appeared in JDK-1.2beta4-H.

--> echo $JAVA_HOME
/export/ld14/java/dest/jdk1.2b4J/solaris
--> java -fullversion
java full version "JDK-1.2beta4-J"
--> setenv CLASSPATH ${JAVA_HOME}/lib/tools.jar:.
--> javac a.java
--> java a
