I do not have an osgi AS7 setup available thus hard for me to reproduce this.
Can you try enabling debugging via standalone.sh ?
You can do that by uncommenting
#JAVA_OPTS="$JAVA_OPTS -Xrunjdwp:transport=dt_socket,address=8787,server=y,suspend=n"
in standalone.conf or standalone.conf.bat if you are on windows.
then it should be running under similar circumstances as from the tools.
If that does not fail then do please open a bug at https://jira.jboss.org/jira/browse/JBIDE with steps to reproduce
(mini osgi app that reproduces it would be great!)
thanks,
