TeamPlatform.startup courses NullPointerException

Melanie Finke (77●2●15●20) | asked Mar 08 '12, 5:14 a.m.
Hello,

I'm using the Rational Team Concert Version 3.0.1 and the Plain Java API 3.0.1.2 .

While starting up the TeamPlatform 
TeamPlatform.startup();


the following Exception appears.

java.lang.NullPointerException

Because on top stands something with VersionString I tried the Java API 3.0.1, but the same Exception occured.

Despite of this Exception I am connected and can read Workitems through it. Does it course any harm?

Kind regards

This seems to be a bug. The plugin.xml file within the com.ibm.team.scm.common bundle contains the following line: 

[dtoEvolution componentVersion="3.0"]


where the attribute modelVersion is missing. So the invocation of com.ibm.team.repository.common.internal.util.EvolutionDescriptor#getModelVersion() returns null. This null-value is used for comparison within the com.ibm.team.repository.common.internal.util.VersionStringComparator. Unfortunately, this comparator is not able to handle null values.

So one of those (a missing modelVersion or the comparator) have to get fixed.

I get the same (non-blocking) NullPointerException running anttask "startBuildActivity" (RTC 3.0.1.1). But it seems to be caused by switching to Java 1.7.0_03. No problems when building using Java 1.6.0_29.
Anyone recognizes this JDK relation???

I've not tried combination of latest RTC (3.0.1.2?) with latest JDK (1.7.0_04) yet.

I'm hitting the same problem with IBM JVMs:

IBM JVM Java 1.6.0 SR9 works fine.
IBM JVM Java 1.7.0 SR4, startBuildActivity hits java.lang.NullPointerException at com.ibm.team.repository.common.internal.util.VersionStringComparator.getIntegerParts(VersionStringComparator.java:71)

I have a similar problem; To hide this from the user I redirect stderr and stdout before the call and then restore them afterwards.

// Stop bug displaying
// at com.ibm.team.repository.common.internal.util.VersionStringComparator.getIntegerParts(VersionStringComparator.java:71)

                // Capture for restore
PrintStream stderr = System.err;
PrintStream stdout = System.out;
try {
                        // Redirect output to null (don't capture)
System.setErr(null);
System.setOut(null);
                        // Get RTC connection
connection = TeamPlatform.getTeamRepositoryService().getTeamRepository(repository);
}
finally {

                        // Ensure we restore afterwards
System.setErr(stderr);
System.setOut(stdout);
}
