Unable to load class TapestryComponentHyperlinkDetector #13

Closed balapal closed 10 years ago

balapal commented 10 years ago

Started to get these error messages today.

Error message I see:

The 'com.anjlab.eclipse.tapestry5.hyperlink.TapestryComponentHyperlinkDetector' extension from plug-in 'com.anjlab.eclipse.tapestry5' to the 'org.eclipse.ui.workbench.texteditor.hyperlinkDetectors' extension point failed to load the hyperlink detector. Plug-in com.anjlab.eclipse.tapestry5 was unable to load class com.anjlab.eclipse.tapestry5.hyperlink.TapestryComponentHyperlinkDetector. An error occurred while automatically activating bundle com.anjlab.eclipse.tapestry5 (6).

Eclipse version and plugins:

Spring Tool Suite

Version: 3.4.0.RELEASE Build Id: 201310051818

Eclipse 3.8.2 Tapestry plugin version: 2.2.4

Hmm, after a few restarts (some were with -clean) the issue seems to be gone.

Thanks for reporting, I'll fix this NPE in future release.

balapal commented 10 years ago

It looks like that this happens if I leave open a Mylyn task when closing/restarting eclipse.

I use mylyn with bitbucket connector: Mylyn Bitbucket Connector 0.5.0.201401031449 org.eclipse.mylyn.bitbucket.feature.feature.group Peter P. Lupo
