Description
|
Steps to reproduce :
1) Install the JDK 1.3.1_02 from:
/java/re/jdk/1.3.1_02/promoted
2) Download the attachment "TestCase.java".
3) Compile the testcase
<JDK1.3.1_02>/bin/javac TestCase.java
4) Execute the testcase
<JDK1.3.1_02>/bin/java -server -Xcomp TestCase
java version "1.3.1_02-ea"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.1_02-ea-b01)
Java HotSpot(TM) Server VM (build 1.3.1_02-ea-b01, compiled mode)
We get the following error:
Exception in thread "CompileThread0" java.lang.OutOfMemoryError: requested 67108876
The test fails on x86 platforms (Windows 2000, Linux customer 7.1 and IA Solaris 8) with the -server -Xcomp flag only. The failure doesn't happen with client -Xcomp or -Xmixed and server -Xmixed. The testcase passes on 1.3.1_01, 1.3.1_01a and 1.4-b84 JDKs.

Evaluation

Testcase exhibited problem in the server compiler where we were ending
up in an infinite loop during the node creation in the graph. The fix
is to add a check so that we don't end up in an infinite loop. Testcase
exhibited the failure on INTEL architecture only, but the problem is generic
and could have happened on SPARC also.
