Error or mistake? What does this unreadable string mean in the Maven release?

Question

The output Maven installin Eclipsewrites several lines like this:

[ERROR]  50% 21/31 build modules 52% 22/31 build .... 

I put here only part of one of these lines, they are very long. You can see all the output in Google Drive . Find [ERROR] there.

I do not like these error messages without knowing what they are about. What if they signal something really bad? Or just bad? Or are these just Maven Halloween jokes? I'm afraid not.

All workspace projects seem installedOK

[INFO] ca-sp .............................................. SUCCESS [ 24.287 s]
[INFO] ca-cm .............................................. SUCCESS [ 21.186 s]
[INFO] ca ................................................. SUCCESS [ 20.438 s]
[INFO] ca-tests ........................................... SUCCESS [  1.340 s]

But

after that, at the end, I see:

FATAL ERROR in native method: JDWP Can't allocate jvmti memory, jvmtiError=JVMTI_ERROR_INVALID_ENVIRONMENT(116)
FATAL ERROR in native method: JDWP on getting class status, jvmtiError=JVMTI_ERROR_WRONG_PHASE(112)

The following lines are red:

JDWP exit error JVMTI_ERROR_WRONG_PHASE(112): on getting class status [util.c:1285]
JDWP exit error JVMTI_ERROR_INVALID_ENVIRONMENT(116): Can't allocate jvmti memory [util.c:1799]
ERROR: JDWP unable to dispose of JVMTI environment: JVMTI_ERROR_INVALID_ENVIRONMENT(116)
