On startup screen, click "Create New Dataset" to launch wizard, then click
"Introduction to Ecological Metadata" link to open HTML viewer.

Any mouseover or resizing on the text pane results in streams and sreams of
nullpointer stacktraces that make the UI unresponsive.

Haven't looked in great detail ,but appears to be due to a known jdk1.5 bug (Bug
ID #5089077) - see:

which occurs when relative text sizes are used in HTML documents

Possible fixes -

a) better way is to change the code to get rid of the exception (e.g, see
workaround shown at foot of bug page linked above)
b) least-desirable way is to edit HTML/CSS files so relative font sizes aren't
used (I'm guessing some fonts are set as 1em etc instead of 12px etc)

This is an important one to fix for the 1.6 release because JDK 1.5 is going to
be more and more common.

and 1.5.0_03
Matthew's jdk version was 1.5.0_02

Matthew says able to reproduce the bug on machines where jalama plugin is
installed. Hence it is related to the Jalama plugin.

Decreasing priority and assigning bug to Matthew.

Are we even using the Jalama plugin?

Actions #5

Updated by Matt Jones almost 14 years ago

No, the Jalama plugin is way out of date, and we are not using it. This bug can be closed I think.

Actions #6
